Synthesis and SAXS Characterization of Sulfonated Styrene-Ethylene/Propylene-Styrene Triblock Copolymers

Abstract

Novel, short outer block sulfonated SEPS triblock copolymers were synthesized, characterized via DMA and SAXS. The polymers exhibited microphase separation in which the minor component, sulfonated polystyrene formed a dispersed, hard phase in the soft, ethylene/propylene rubber matrix. The interdomain spacing measured by SAXS allowed an analysis of the effects of the rubber block molecular weight and neutralization.
