    ABSTRACT: A new method to prepare the polymer electrolytes for lithium-ion batteries is proposed. The polymer electrolytes were prepared by reacting poly(phosphazene)s (MEEPP) having 2-(2-methoxyethoxy)ethoxy and 2-(phenoxy)ethoxy units with 2,4,6-tris[bis(methoxymethyl)amino]-1,3,5-triazine (CYMEL) as a cross-linking agent. This method is simple and reliable for controlling the cross-linking extent, thereby providing a straightforward way to produce a flexible polymer electrolyte membrane. The 6 mol % cross-linked polymer electrolyte (ethylene oxide unit (EO)/Li = 24:1) exhibited a maximum ionic conductivity of 5.36 × 10−5 S cm−1 at 100 °C. The 7Li linewidths of solid-state static NMR showed that the ionic conductivity was strongly related to polymer segment motion. Moreover, the electrochemical stability of the MEEPP polymer electrolytes increased with an increasing extent of cross-linking, the highest oxidation voltage of which reached as high as 7.0 V. Moreover, phenoxy-containing polyphosphazenes are very useful model polymers to study the relationship between the polymer flexibility; that is, the cross-linking extent and the mobility of metal ions. © 2015 Wiley Periodicals, Inc.

    ABSTRACT: A series of amphiphilic silica/fluoropolymer nanoparticles of SiO2-g-P(PEGMA)-b-P(12FMA) were prepared by silica surface-initiating atom transfer radical polymerization (SI-ATRP) of poly(ethylene glycol) methyl ether methacrylate (PEGMA) and poly dodecafluoroheptyl methacrylate (P12FMA). Their amphiphilic behavior, lower critical solution temperature (LCST), and surface properties as protein-resistance coatings were characterized. The introduction of hydrophobic P(12FMA) block leads SiO2-g-P(PEGMA)-b-P(12FMA) to form individual spherical nanoparticles (∼150 nm in water and ∼170 nm in THF solution) as P(PEGMA)-b-P(12FMA) shell grafted on SiO2 core (∼130 nm), to gain obvious lower LCST at 36–52 °C and higher thermostability at 290–320 °C than SiO2-g-P(PEGMA) (LCST = 78–90 °C, Td = 220 °C). The water-casted SiO2-g-P(PEGMA)-b-P(12FMA) films obtain much rougher surface (125.3–178.4 nm) than THF-casted films (11.5–16.9 nm) and all SiO2-g-P(PEGMA) films (26.8–31.3 nm). Therefore, the water-casted surfaces exhibit obvious higher water adsorption amount (Δf = −494 ∼ −426 Hz) and harder adsorbed layer (viscoelasticity of ΔD/Δf = −0.28 ∼ −0.36 × 10−6/Hz) than SiO2-g-P(PEGMA) films, but present loser adsorbed layer than THF-casted films (ΔD/Δf = −0.29 ∼ −0.63 × 10−6/Hz). While, the introduction of P(12FMA) segments does not show obviously reduce in the protein-repelling adsorption of SiO2-g-P(PEGMA)-b-P(12FMA) films (△f = −15.7 ∼ −22.3 Hz) compared with SiO2-g-P(PEGMA) films (△f = −8.3 ∼ −11.3 Hz) and no obvious influence on water adsorption of ancient stone. Therefore, SiO2-g-P(PEGMA)-b-P(12FMA) is suggested to be used as protein-resistance coatings. © 2015 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem. 2015

    ABSTRACT: Ester-free silane and siloxane-based thiol monomers were successfully synthesized and evaluated for application in thiol-ene resins. Polymerization reaction rates, conversion, network properties as well as degradation experiments of those thiol monomers in combination with triallyl-1,3,5-triazine-2,4,6(1H,3H,5H)-trione (TATT) as ene component were performed and compared with formulations containing the commercially available mercaptopropionic ester-based thiol pentaerythritol tetra-3-mercaptopropionate. Kinetic analysis revealed appropriate reaction rates and conversions reaching 90% and higher. Importantly, storage stability tests of those formulations clearly indicate the superiority of the synthesized mercaptans compared with pentaerythritol tetra-3-mercaptopropionate/TATT resins. Moreover, photocured samples containing silane-based mercaptans provide higher glass transition temperatures and withstand water storage without a significant loss in their network properties. This behavior together with the observed excellent degradation resistance of photocured silane-based thiol/TATT formulations make these multifunctional mercaptans interesting candidates for high-performance applications, such as dental restoratives and automotive resins. © 2015 Wiley Periodicals, Inc.

    ABSTRACT: A simple and convenient method for the synthesis of end functionalized polylactides (PLAs) under mild conditions by ring opening polymerization (ROP) in the absence of potentially toxic catalysts is described. Various alcohols were used as initiators in combination with Ca[N(SiMe3)2]2(THF)2 as the precatalyst in THF at room temperature. Tailored end functionalities were obtained in a controlled fashion. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-ToF-MS) and electrospray ionization quadrupole time of flight mass spectrometry (ESI-Q-ToF-MS) analysis were performed to investigate the end groups. The results confirmed that the end group fidelity was maintained in the isolated PLAs. © 2015 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem. 2015

    ABSTRACT: In this study, a facile method to fabricate reduction-responsive core-crosslinked micelles via in situ thiol-ene “click” reaction was reported. A series of biodegradable poly(ether-ester)s with multiple pendent mercapto groups were first synthesized by melt polycondensation of diol poly(ethylene glycol), 1,4-butanediol, and mercaptosuccinic acid using scandium trifluoromethanesulfonate [Sc(OTf)3] as the catalyst. Then paclitaxel (PTX)-loaded core-crosslinked (CCL) micelles were successfully prepared by in situ crosslinking hydrophobic polyester blocks in aqueous media via thiol-ene “click” chemistry using 2,2′-dithiodiethanol diacrylate as the crosslinker. These PTX-loaded CCL micelles with disulfide bonds exhibited reduction-responsive behaviors in the presence of dithiothreitol (DTT). The drug release profile of the PTX-loaded CCL micelles revealed that only a small amount of loaded PTX was released slowly in phosphate buffer solution (PBS) without DTT, while quick release was observed in the presence of 10.0 mM DTT. Cell count kit (CCK-8) assays revealed that the reduction-sensitive PTX-loaded CCL micelles showed high antitumor activity toward HeLa cells, which was significantly higher than that of reduction-insensitive counterparts and free PTX. This kind of biodegradable and biocompatible CCL micelles could serve as a bioreducible nanocarrier for the controlled antitumor drug release. © 2015 Wiley Periodicals, Inc. J. Polym.

    ABSTRACT: Polyethylene glycol (PEG) is widely used as a carrier to improve the pharmaceutical properties of drugs with low molecular weight. However, PEG has few functional groups (usually two) for drug conjugation and the resulting low drug content (1–2%) has hampered its clinical applications. For this study, we synthesized biodegradable poly(ethylene glycol-co-anhydride). This polyester-based polymer possesses multiple carboxylic acid groups that can be used as facile drug carriers. Two anticancer drugs, camptothecin (CPT) and doxorubicin (DOX) were loaded into the carrier and their releasing properties and in vitro anticancer activities were studied. The polymer–drug conjugates exhibited esterase-promoted degradation and drug release. Their cytotoxicity against the human ovarian cancer cell line SKOV-3 was comparable to unconjugated drugs. © 2015 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem. 2015

    ABSTRACT: The synthesis and self-assembling of a thermoresponsive conjugate of hyaluronic acid (HA) and poly(N-vinylcaprolactam) (PVCL) is reported. Both polymers were end functionalized: HA via reductive amination, thereby introducing an azide endgroup to the chain end, and PVCL via thioetherification to introduce a propargyl group. The two were coupled with a copper assisted “click” reaction into a bioconjugate composed of HA blocks with the molar mass 3,600 g mol−1 (1618 saccharide units) and PVCL blocks of 3,500 g mol−1 (∼25 repeating units). The cloud point temperature measured by transmittance was 50–51 °C in water. The calorimetrically observed phase transition temperature of PVCL in the conjugate increased by 2 °C to 47.7 °C, whereas the enthalpy of the phase transition was unaffected by the conjugation. HA-PVCL conjugate self-assembles in water upon heating into monodisperse, colloidally stable, hollow spherical particles whose size may be tuned with the heating rate of the solution. Slow and fast heating resulted in vesicles with the hydrodynamic radii of 443 or 275 nm, respectively. The heating rate did not, however, affect the cloud point. Salt did not noticeably affect the size of the polymer particles, presumably because of interactions between the HA and PVCL blocks. © 2015 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.

    ABSTRACT: In this study, a facile strategy for the preparation of thermo- and pH-responsive nanogels through reversible addition–fragmentation transfer (RAFT) crosslinking copolymerization of ionic liquid-based monomers is demonstrated. The use of chain transfer agents (CTAs) containing carboxyl group in the RAFT polymerizations is the key to producing highly thermoresponsive nanogels. Experimental results demonstrate that the critical gelation temperature of the as-prepared nanogels can be tuned by adjusting the feed ratio of monomer and CTA. Variable temperature Fourier transform infrared measurements and control experiments indicate that hydrogen-bonding interactions between the carboxyl groups of CTAs are responsible for the thermoresponsive behaviors of poly(ionic liquid) (PIL)-based nanogels. Furthermore, PIL-based nanogels are also found to be pH-sensitive, and can be further decorated by poly(N-isopropylacrylamide) (PNIPAAm) via surface grafting polymerization. PNIPAAm-grafted nanogel aqueous solutions can be reversibly transformed into macrogels upon a change in temperature. © 2015 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem. 2015

    ABSTRACT: A bicomponent initiation system consisting of 2,2,6,6-tetramethylpiperidine-N-oxyl (TEMPO) and the water soluble initiator potassium persulfate (KPS) was used to develop a robust and versatile semibatch emulsion polymerization process to obtain polystyrene (PS) latexes with solids contents of 5–40 wt %. A window of operating conditions was found that yielded high conversion (>95%) stable latexes and well controlled polymers, overcoming limitations found in previous attempts at developing similar processes using TEMPO. The critical parameters studied were surfactant concentration, monomer concentration in the nucleation step and the monomer feed rate in the semibatch step. Methyl acrylate (MA) was used in the nucleation step to improve the nitroxide efficiency (NEff). Latexes having molecular weight distribution (MWD) with dispersity (Đ) lower than 1.5, average particle size (Dp) from ≈32 to ≈500 nm, nitroxide efficiencies NEff up to ≈1.0 and monomer conversions >90% were obtained in less than 12 h with solids contents up to 40 wt %. These results constitute a significant advance over prior efforts in TEMPO-mediated polymerization in aqueous dispersions. © 2015 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem. 2015

    ABSTRACT: Isoprene polymerization and copolymerization with ethylene can be carried out by using cationic half-sandwich fluorenyl scandium catalysts in situ generated from half-sandwich fluorenyl scandium dialkyl complexes Flu'Sc(CH2SiMe3)2(THF)n, activator, and AliBu3 under mild conditions. In the isoprene polymerization, all of these cationic half-sandwich fluorenyl scandium catalysts exhibit high activities (up to 1.89 × 107 g/molSc h) and mainly cis−1,4 selectivities (up to 93%) under similar conditions. In contrast, these catalysts showed different activities and regio-/stereoselectivities being significantly dependent on the substituents of the fluorenyl ligands in the copolymerization of isoprene with ethylene under an atmosphere of ethylene (1 atm) at room temperature, affording the random copolymers with a wide range of cis−1,4-isoprene contents (IP content: 64 − 97%, cis−1,4-IP units: 65 − 79%) or almost alternating copolymers containing mainly 3,4-IP-alt-E or/and cis−1,4-IP-alt-E sequences. Moreover, novel high performance polymers have been prepared via selective epoxidation of the vinyl groups of the 1,4-isoprene units in the IP-E copolymers. © 2015 Wiley Periodicals, Inc. J. Polym.

    ABSTRACT: Two donor–acceptor conjugated polymers, PTSSO-TT and PTSSO-BDT, composed of acenaphtho[1,2-c]thiophene-S,S-dioxide (TSSO) as a new electron acceptor and thienothiophene (TT) or benzo[1,2-b:4,5-b']dithiophene (BDT) as electron donors, were synthesized with Stille cross-coupling reactions. The number-averaged molecular weights (Mn) of PTSSO-TT and PTSSO-BDT were found to be 15100 and 26000 Da, with dispersity of 1.8 and 2.4, respectively. The band-gap energies of PTSSO-TT and PTSSO-BDT are 1.56 and 1.59 eV, respectively. The HOMO levels of PTSSO-TT and PTSSO-BDT are −5.4 and −5.5 eV, respectively. These results indicate that the inclusion of TSSO accepting units into polymers is a very effective method for lowering their HOMO energy levels. The field-effect mobilities of PTSSO-TT and PTSSO-BDT were determined to be 1.5 × 10−3 and 4.5 × 10−4 cm2 V−1 s−1, respectively. A polymer solar cell device prepared with PTSSO-TT as the active layer was found to exhibit a power conversion efficiency (PCE) of 3.79% with an open circuit voltage of 0.71 V under AM 1.5 G (100 mW cm−2) conditions. © 2015 Wiley Periodicals, Inc.

    ABSTRACT: In an attempt to create a polymer brush-based platform for the systematic study for anti-biofouling surfaces, the benefits of surface initiated, visible light-mediated radical polymerization are utilized to fabricate well-defined, chemically ambiguously patterned surfaces. A variety of analytical tools are used to illustrate the precise tuning of surface chemistry and thoroughly characterize spatially well-defined, hydrophilic/hydrophobic surfaces composed of poly(ethylene glycol methacrylate) and poly(trifluoroethyl methacrylate) with chemical definition on the micron scale. Advantages of both visible light-mediated photopolymerization and traditional copper-catalyzed atom transfer radical polymerization are combined to achieve both high spatial control and expanded monomer tolerance. © 2015 Wiley Periodicals, Inc.

    ABSTRACT: A series of new functional poly(ethylene-co-vinyl alcohol)-g-polystyrene graft copolymers (EVAL-g-PS) with controlled molecular weight (Mn = 38,000–94,000 g mol−1) and molecular weight distribution (Mw/Mn = 2.31–3.49) were synthesized via a grafting from methodology. The molecular structure and component of EVAL-g-PS graft copolymers were confirmed by the analysis of their 1H NMR spectra and GPC curves. The porous films of such copolymers were fabricated via a static breath-figure (BF) process. The influencing factors on the morphology of such porous films, such as solvent, temperature, polymer concentration, and molecular weight of polymer were investigated. Ordered porous film and better regularity was fabricated through a static BF process using EVAL-g-PS solution in CHCl3. Scanning electron microscopy observation reveals that the EVAL-g-PS graft copolymer is an efficient compatibilizer for the blend system of low-density polyethylene/polystyrene. © 2015 Wiley Periodicals, Inc.

    ABSTRACT: The rapid and uncontrolled nature of network formation from di(meth)acrylate monomers produces high shrinkage stress and results in polymers with oftentimes brittle mechanical properties. Methods for regulating polymerization and network formation are sought. One option is the use of addition–fragmentation chain transfer (AFCT) agents, which are well known to control molecular weight and molecular weight distribution of monofunctional (meth)acrylates. A series of novel and previously described AFCT reagents were synthesized and screened with laser flash photolysis to determine reactivity. Well-performing AFCT reagents were then tested in polymerizations with monofunctional and difunctional methacrylates. With monofunctional monomers, the molecular weight and polydispersity of the resultant linear polymers tend to decrease with the addition of AFCT agent. In copolymerization with dimethacrylate monomers, the AFCT agents were found to substantially lower and sharpen the glass transition. Sharpness of the glass transition is here indicative of a more regular and homogenous network. After coupling of the instruments, photorheology was performed simultaneously with real-time IR to show an increase in monomer conversion at the time of gelation, which appears to have a positive effect on reducing shrinkage stress. © 2015 Wiley Periodicals, Inc.

    ABSTRACT: A new sulfonated dendrimer with an arylene ether sulfone backbone has been synthesized, fully characterized, and blended with PBIOO® to prepare acid-base proton-conducting membranes under different conditions and with different composition ratios. Water-soluble sulfonated hyperbranched polyglycerols of different molecular weights were also used as the acidic components. Membrane properties such as ion-exchange capacity, water uptake, thermal stability, proton conductivity, and morphology have been studied and discussed. The nature of the acidic component and the morphology of the membranes had a marked influence on the final properties. © 2015 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem. 2015
