This paper deals with the synthesis of multiblock copolymer of styrene and propylene oxide by coupling reaction of telechelic dihydroxyl polystyrene, TDI and polypropylene glycol and also the study of their properties in order to obtain a new polymeric material containing no double bonds for use as thermoplastic elastomer and a compatibilizer in the blending of epichlorohydrin rubber and polystyrene. When epichlorohydrin rubber was blended with polystyrene alone, the tensile strength was rather low and the permanent set somewhat large. However, if 1-2% of the multiblock copolymer of styrene and propylene oxide was added to the blend, the mechanical properties were improved quite a lot.
