Abstract:

The copolymerization of styrene--isoprene with Lewis bases and isobutylene--p-chorostyrene with Lewis acids shows a dependence of copolymer composition on solvents and counterions. The work reported in this thesis was designed to shed light on two questions 1 Is the effect of solvent and catalyst of general significance in ionic copolymerization. 2 Are ionic copolymerizations generally ideal. Copolymerizations were performed with styrene -- alpha - methylstyrene, styrene--p-methylstyrene, styrene--p-methoxystyrene, and p-methylstyrene--pmethoxystyrene. Various Lewis acids and bases were used in several solvents. Reactivity ratios were calculated for all but the styrene-alpha-methylstyrene copolymers.
