Copolymerization Behaviors of p-Substituted Phenyl Allyl Ethers and Sulfides

Abstract

Radical copolymerizations of p-substituted phenyl allyl ethers and sulfides with acrylonitrile (M1) have been investigated. Plots of log 1/r, against a values gave the following results: p= -0.35 for phenyl allyl ethers and p=0.17 for phenyl allyl sulfides. Meanwhile, the Hammett p values for the chain transfer reaction of these ethers and sulfides toward polystyryl radical were calculated to be 1.28 and 0.08, respectively. From the results obtained, the nature of the transition states of the propagation and the chain transfer reactions are discussed.
