Patent
An aqueous dispersion of a vinyl ester/ethylene copolymer is prepared by emulsion copolymerization of a monomer mixture comprising a vinyl ester, ethylene and a polyvinyl alcohol stabilizing system consisting essentially of (a) about 0.5 to about 3 wt. % based on the total monomer weight of a first polyvinyl alcohol having a degree of hydrolysis of...
Article
Oligo(vinylamine) (OVAm) can be synthesized from oligo(N-vinylformamide) (OVFA) by hydrolysis of the formamide groups. The cationic polymerization of VFA is initiated with iodine, bromine, trifluoromethanesulfonic acid, or trimethylsilyl triflate in toluene at various temperatures. Chain structures, head group functionality, and MWD of the OVFA are...
Article
A critical review of former investigations on the cationically induced oligomerization of N-vinylformamide points out that some of the results are not in agreement with the model of an cationic propagation mechanism. Special attention in the discussion of the results is given on the chain structure of the oligo(N-vinylformamide)s. In comparison wit...

Gegenstand der vorliegenden Arbeit ist die Untersuchung der kationisch initiierten Oligomerisation von N-Vinylformamid mit Iod, Brom, Trifluormethansulfonsäure und Trifluormethansulfonsäure-trimethylsilylester. Quantenchemische Berechnungen zur Konformation und zur Elektronendichteverteilung von N-Vinylformamid, sowie zu seiner Reaktion mit Elektro...
Article
Summary Bromine was found to be an effective initiator for the cationically induced oligomerization of vinylformamide (VFA). Oligomeric products with molecular weights between 200 and 1500 g/mol were obtained. The structures of the oligo(vinylformamides) (OVFA) were investigated by means of NMR spectroscopy, GPC, and MALDI-TOF-MS. The influence of...
Article
The electron density distributions of the four possible configurational isomers of the monomer vinylformamide (VFA) and of the cationically propagating species were examined by means of quantum chemical calculations. They show that the electrophilic attack of the propagating chain at the carbonyl oxygen of the VFA monomer is kinetically controlled...
Article
Vinylformamide (VFA) is cationically polymerized in various solvents at 273 K and reaction temperature by the following initiators: iodine, bis(4-methoxyphenyl)-methyl chloride/silica, triphenylmethyl chloride/silica, and trimethylsilyl triflate. In every case defined oligomers with narrow molecular weight distribution are obtained in moderate yiel...
