REACTIVITY OF ACRYLATES IN COPOLYMERIZATI ON WITH AMINOSTYRENES

For a number of acrylates with various lengths of alkyl chain C-x (x = 1-18) reactivity ratios in copolymerization with aminostyrenes (m- an d p-dimethylaminostyrenes and p-acetylaminostyrene) were deter mined. The dependence of reactivity df acrylate monomers with respect to poly mer radicals with aminostyrene end groups on x was found to show a max imum. Correlation dependences of the reactivity ratios of acrylate mon omers on x and sigma (the Hammett constant of substituent in aminostyr ene) were plotted. The reactivities' of aminostyrenes were calculated according to the Alfley-Price treatment, and the parameters of microst ructure of the resulting copolymers were determined.
