摘要：
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 hah 95; andB) 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; andC) 0-60 weight percent based on the weight of (A) and (B) of a reinforcing filler.The products are prepared by melting together polyurethane elastomers (A) and (B) at temperatures of from 140.degree.-250.degree. C., preferably in an extruder, and are most preferred for the preparation of ski boots and injection molded articles for motor vehicles.
