Abstract

Abstract 1. Thermoplastic moulding compositions comprising I. 30-94% by weight of at least one polyamide, II. 70-3% by weight of a graft product prepared from a) 50-95% by weight of a cross-linked polymer of butadiene and/or subst. butadiene, which can optionally be composed to an extent of up to 40% by weight of styrene and/or acrylonitrile, as the graft substrate, and b) 5-50% by weight of graft monomers of alpha) 3-100 by weight of an ester of (meth)acrylic acid, beta) 0-80% by weight of styrene and gamma) 0-80% by weight of (meth)acrylonitrile, wherein the gel content of the graft substrate should be => 70%, measured in toluene, the graft yield should be G >= 0.15 and the average particle diameter of the graft copolymer should be >= 0.1 mu m, III. 20-3% by weight of a plasticiser customary for polyamide and optionally other customary additives, the sum of I. -III. and of a) and b) and of, alpha) - gamma) having in each case to equal 100% by weight.
