Abstract

Thermoplastic elastomers of high strength, high elasticity and good dyeability, the incorporated elastomeric particles of which have an average particle diameter of 0.05 to 5 .mu.m, from propylene homopolymers and/or propylene copolymers, elastomeric C.sub.2 to C.sub.8 olefin copolymers and/or terpolymers and multifunctional, unsaturated monomers are formed by a method, for which mixtures of propylene homopolymers and/or propylene copolymers, elastomeric C.sub.2 to C.sub.8 olefin copolymers and/or terpolymers and readily volatile C.sub.4 to C.sub.7 dienes are reacted in the melt. The thermoplastic elastomers, as well as mixtures with conventional polyolefins, are suitable for use in the vehicle industry, in the domestic appliances industry, in the building sector and in medical technology.
