ABSTRACT:
A process for making a thermoplastic polyurethane material comprising the steps of casting an NCO-terminated prepolymer with 1,4-butanediol to form a casting composition; extruding the casting composition to form at least one strand of a polyurethane elastomer; pelletizing the at least one strand of said polyurethane elastomer to form at least one pellet; and processing the at least one pellet to form a thermoplastic article.
