✦ Synopsis

Radical copolymerization of some methyl a-acyloxyacrylates and vinyl monomers has been studied using an azo initiator in benzene at 60 °C. It is found that the Q and e values of methyl a-acyloxyacrylates are in the ranges 0.47±1.65 and 0.51±0.99, respectively, and the relative reactivity of the acrylates towards the propagating radicals of styrene in copolymerization is correlated to the modi®ed Taft equation considering the steric and electronic effects. Copolymerization of methyl a-acetoxyacrylate and vinyl monomers shows that the relative reactivity of the vinyl monomers for the attack of poly (methyl a-acetoxyacrylate) radical tends to increase with increasing Q values of the vinyl monomers.
