Mo3565 LeA 27,690 THERMOPLASTIC COMPOSITIONS OF POLYURETHANES AND PARTLY CROSSLINKED ALKYL ACRYLATE COPOLYMERS ABSTRACT OF THE DISCLOSURE The present invention is directed to a thermoplastic composition which is a blend of A) a thermoplastic polyurethane and B) an at least partly crosslinked alkyl acrylate copolymer of a C1-6 alkyl acrylate and a monomer selected from the group consisting of acrylonitrile, styrene, vinyl acetate, C1-6 alkyl methacrylates and mixtures thereof. The preferred compositions also contain copolymer selected from the group consisting of C1) a thermoplastic graft product of a rubber component having a glass transition temperature below 0°C, which serves as the graft base, and at least one graft monomer selected from the group consisting of styrene, .alpha.-methyl styrene, acrylonitrile and C1-6 alkyl methacrylate, C2) a rubber-free resin copolymer of styrene or .alpha.-methyl styrene with acrylonitrile, C3) mixtures thereof.
