Thermoplastic elastomer with high resistance, elasticity and good paintability and high impact resistant polymer blends prepared therefrom

Thermoplastic elastomers of high strength, elasticity and good colorability, whose embedded elastomer particles have a mean particle diameter of 0.05 to 5 microns, of propylene homopolymers and / or propylene copolymers, elastomeric C2-C8thOlefin co- and / or terpolymers and polyfunctional unsaturated monomers are formed in a process in which mixtures of propylene homopolymers and / or propylene copolymers, elastomeric C2-C8thOlefin co- and / or terpolymers and volatile C4-C7Serve to be reacted in the melt. The thermoplastic elastomers and mixtures with conventional polyolefins are suitable for use in the automotive industry, household appliance industry, in the construction sector and in medical technology.
