Abstract

Abstract: The phase transfer catalytic action and compatibilizing action of the (styrene-bu-tadiene-oxyethylene) multiblock copolymers and the conductivity of the complex of them with LiClO₄ were studied.The results show that the LiClO₄ complex of the multiblock copolymers shows a conductivity of about 4×10^-4 S·cm^-1 at 35℃.The multiblock copolymers possess a good phase transfer catalytic ability in Williamson reaction and can be used as compatibilizer in blending epichlorohydrin rubber with ABS.

Key words: Muitiblock copolymer, Solid polymer electrolyte, Phase transfer catalysis, Com-patibilizer, Polyoxyethylene
