Effect of solvent on chain propagation and termination reaction rates in radical polymerization

Primary radical termination and unimolecular termination in the heterogeneous polymerization of acrylamide initiated by a fluorinated azo-derivative initiator: A kinetic study

“…From different k p values of acrylamide in formamide and dimethyl sulfoxide, 39 we deduce that K is 5-10 s Ϫ1 . The lifetime of the chain before occlusion is then between 0.1 and 0.2 s, which is the same order of magnitude as that of radicals in classical polymerization.…”

Multi‐Component Kinetic Modeling for Controlling Local Compositions in Thermosensitive Polymers

“…For the monoacid monomers, homopolymerization rates in water at 70 8C can either be found directly or estimated from literature data using the Arrhenius equation. [31][32][33] Direct data are also available for the homopolymerization of the cationic monomers. [29] FA data are estimated from the polymerization of fumaric acid diethyl ester in benzene; [34] the tabulated data are corrected for the kinetic impact of the esterification and the organic solvent according to effects tabulated in the corresponding acrylic acid data.…”

Effect of Phenols on the Free-Radical Photopolymerization of Vinyl Monomers in Aqueous Solution

“…[10] Moreover, it is well recognized that k p for this monomer is a function of pH and it changes in an unusual way with temperature. [12,13] Here, we used k p = 4 020 m -1 N s -1 for acrylamide, a value recently measured at pH 4 employing pulsed-laser polymerization, [14] which is a method that can be considered as more accurate. Values of k tr for the different phenols are included in Table 1.…”
