Article
We have successfully prepared an elastomeric material exhibiting excellent temperature-controlled self-healing characteristics. A synthetic procedure is provided to graft siloxane chains with maleimidocarboxyphenyl functional groups. A furan-modified polyhedral oligomeric silsesquioxane with flexible tethers was also synthesized to cross-link the s...
Article
Olefin block copolymers (OBCs) are new class of thermoplastic elastomers having low glass transition temperature soft blocks and highly crystalline hard blocks synthesized by reversible chain shuttling between two catalysts with considerably different comonomer responses through a chain transfer agent. Theoretical representation of kinetics and mic...
Article
The introduction of functional groups through radical copolymerization under starved‐feed conditions is a cost‐effective means to produce acrylate resins for coatings applications. The semi‐batch recipes often include a large fraction of nonfunctional acrylates and methacrylates, with a low percentage of functional comonomer added to become statist...
Article
Secondary reactions significantly affect acrylate polymerization rates as well as the architecture of polymer produced by high‐temperature solution radical polymerization. This impact is amplified under the semi‐batch starved‐feed policy used to keep monomer concentration low. Thus, the importance of intramolecular chain transfer (backbiting) is si...
Article
Knowledge of the average composition and molecular weights of copolymers containing functional groups is often not enough to ensure product quality, as the distribution of the reactive moieties among the chains affects performance. This work couples a kinetic Monte Carlo model, previously verified as providing an accurate description of the semi-ba...
Article
Functional acrylic resins for the coatings and adhesives industry are often synthesized by radical solution copolymerization at high temperatures (>120 °C) using starved-feed semibatch operation. The kinetic Monte Carlo (KMC) stochastic modeling technique has emerged as a method to represent the placement of the functional comonomer units across th...
Article
While Kinetic Monte Carlo (KMC) techniques provide a powerful means to model polymer microstructure, the associated computational cost has been a barrier to its wide-spread adoption. The case of radical semi-batch polymerization under starved-feed policy is a particularly challenging application: at the initial stage, a large simulation volume is r...

Elastomeric polymeric networks exhibiting excellent temperature-controlled self-healing characteristics & recyclability were prepared. A facile synthetic procedure was followed to graft siloxane chains with maleimidocarboxy phenyl functional groups. A furan-modified polyhedral oligomeric silsesquioxane with flexible tethers was also synthesized to...

Objectives We developed the method of Moments mod-eling based on previous approach of Zhang and coworkers which is reliable to measure chain shuttling copolymerization to study the effects of reversible transfer reaction in chain shuttling copolymerization of Ethylene and 1-Octene with respect of coordinative chain transfer to chain shuttling polym...
