Linear and three-arm star styrene-b-isobutylene-b-styrene block copolymers were synthesized by living cationic polymerization using ring-substituted di- or tricumyl chloride, respectively, as initiator, TiCl4 as coinitiator, pyridine as an electron donor and 2,6-di-tert-butylpyridine as a proton trap in a 60/40 (v/v) methylcyclohexane/methyl chloride solvent mixture at -80-degrees-C. The polymers had equivalent compositions and segmental molecular weights allowing the effect of molecular geometry on sample morphology and physical properties to be determined. The samples exhibited a dual-phase morphology consisting of cylindrical polystyrene domains dispersed within a matrix of polyisobutylene; polymer geometry was found to have a significan...
