Abstract

Crosslinkable compositions based on polyamide and on α-olefin-vinyl acetate copolymers, where the compositions comprise a crosslinking initiator, and also a co-crosslinking agent, and crosslinkable compositions based on polyamides and on α-olefin-vinyl acetate copolymers, where these compositions comprise a crosslinking initiator and the amount of polyamide in the compositions is <30% by weight. The present invention further relates to the preparation of the crosslinkable compositions of the invention, to the use of the crosslinkable compositions of the invention for the production of thermoplastic elastomers, to a process for the crosslinking of the compositions of the invention to give a thermoplastic elastomer, and also to the thermoplastic elastomers themselves and to their use for the production of mouldings.
