Abstract

Thermoplastic elastomers of good dyeability and high strength and elasticity, the incorporated elastomeric particles of which have and average particle diameter of 0.05 to 5 .mu.m. The thermoplastic elastomers are formed according to a method in which mixtures of propylene homopolymers and/or propylene copolymers, elastomeric C.sub.4 C.sub.12 olefin copolymers and/or terpolymers and C.sub.8 to C.sub.14 diacrylates, C.sub.7 to C.sub.16 diallyl compounds, C.sub.9 to C.sub.15 dimethacrylates, C.sub.7 to C.sub.10 divinyl compounds, C.sub.12 to C.sub.17 acrylate esters of polyalcohols, C.sub.15 to C.sub.21 methacrylate esters of polyalcohols and/or C.sub.9 C.sub.12 triallyl compounds are added to a melt. The thermoplastic elastomers, as well as mixtures of the thermoplastic elastomers with conventional polyolefins, are suitable for use in the vehicle industry, in the domestic appliances industry, in the construction industry and in medical technology.
