    摘要: The instant invention is directed to a thermoplastic synthetic material, comprising:(A) 75 to 97% by weight of a thermoplastic polyurethane and(B) 25 to 3% by weight of a polymer of olefinically unsaturated monomers, wherein component (B) is a graft product of(a) 5 to 35% by weight, based on the graft product, of one or more graft monomers on(b) 65 to 95% by weight, based on the graft product, of an elastomer component serving as graft base which has a second order transition temperature of below -30.degree. C.,the entire component (B) containing less than 50% by weight of the monomers styrene, .alpha.-methyl styrene and acrylonitrile. The instant invention is also directed to a process for the production of the thermoplastic synthetic materials.
