ABSTRACT:
A thermoplastic composition comprising about 10-80 parts by weight total polymers of a multi-block copolyester elastomer having a melting point of from about 100.degree.-200.degree. C. and about 20-90 parts by weight total polymers of a crosslinked chlorosulfonated polyethylene elastomer dispersed in said copolyester elastomer, said chlorosulfonated polyethylene elastomer being crosslinked to an extent such that not more than about 45% by weight of said elastomer is extractable with toluene at 25.degree.0 C.
