Abstract
Radical copolymerizations of styrene (St) with p-substituted-N, N-diethylcinnamamides (I) and also of p-substituted styrenes (II) with methyl vinyl sulfoxide (MVSO) have been carried out in benzene, acetic acid or acetonitrile. The monomer reactivity ratios (r1) were found to be affected by the solvents, p values obtained by using the modified Hammett equation, i. e., log(1/r1) = ρσ + γ ER, were also found to be altered by the solvents. The results are discussed in terms of the solvent effect in the transition state of the propagation reaction.Keywords
