Estimation of Free Radical Polymerization Rate Coefficients using Computational Chemistry
Acrylic free radical polymerization at high temperature proceeds via a complex set of mechanisms, with many rate coefficients poorly known and difficult to determine experimentally. This problem is compounded by the large ...
Critically Evaluated Rate Coefficients in Radical Polymerization – 8. Propagation Rate Coefficients for Vinyl Acetate in Bulk
Propagation rate coefficient values, kp, reported by several groups for radical polymerization of bulk vinyl acetate are critically evaluated. All data are obtained by the combination of pulsed-laser polymerization and ...
Modeling the Synthesis of Butyl Methacrylate Macromonomer by Sequential ATRP-CCTP
The atom transfer radical polymerization of butyl methacrylate mediated by Cu(I)Br/N,N,N′,N″,N″-pentamethyldiethylenetriamine in anisole at 70 °C with the subsequent addition of bis(difluoroboryldiphenylglyoximato)cobalt(II) ...
Investigating the Effectiveness of Reactive Dispersants in Non-Aqueous Dispersion Polymerization
Non-aqueous dispersion (NAD) radical polymerization is used to produce poly(acrylic) nanoparticles (<200 nm) at 60 wt% solids content by a starved-feed semibatch process, with steric stabilization provided by a low molecular ...
Vinyl pivalate Propagation Kinetics in Radical Polymerization
Radical propagation kinetics of the bulk homopolymerizations of vinyl pivalate (VPi) and vinyl benzoate (VBz) have been studied using pulsed-laser polymerization (PLP) combined with size exclusion chromatography (SEC). As ...
Solvent Effects on Radical Copolymerization Kinetics of 2-Hydroxyethyl Methacrylate and Butyl Methacrylate
(MDPI AG, 2019-03)
2-Hydroxyethyl methacrylate (HEMA) is an important component of many acrylic resins used in coatings formulations, as the functionality ensures that the chains participate in the cross-linking reactions required to form ...
