摘要：
A thermoplastic molding composition comprising a thermoplastic polyurethane and an olefinic copolymer is disclosed. The polyurethane component contains ether structural units and units derived from an aliphatic isocyanate. The molecular structure of the copolymer contains units derived from monomers containing olefinic unsaturation. The composition is characterized in the compatibility of its resinous components and in the improved mechanical properties.
