CA 2008812

Abstract of Disclosure The present invention deals with low temperature impact resistant, easily flowing, thermoplastic polyurethane elastomer compositions, comprising: A) 5-95 parts by weight of at least one thermoplastic polyurethane elastomer (A) having a Shore A hardness less han 95; and B) 95-5 parts by weight of at least one thermoplastic polyurethane elastomer (B) having a Shore A hardness greater than 98, whereby the parts by weight of (A) and (B) total 100 parts by weight and C) 0-60 weight percent based on the weight of (A) and (B) of a reinforcing filler. The products are prepared by melting together poly- urethane elastomers (A) and (B) at temperatures of from 140° - 250° C, preferably in an extruder, and are most preferred for the preparation of ski boots and injection molded articles for motor vehicles. -36-
