Novel crosslinkable compositions are provided and are based on thermoplastic polymers and elastomers, these compositions comprising, as crosslinking system, specific organic salts of metal ions. Ionically crosslinked thermoplastic elastomers can be obtained therefrom and have excellent physical properties, high-temperature resistance extending above 150&#xb0; C., and also oil resistance. They can be used for production of moldings.

Crosslinkable compositions, thermoplastic elastomers obtainable therefrom and their use

Crosslinkable compositions based on at least one copolyester as thermoplastic elastomer and on &#x3b1;-olefin-vinyl acetate copolymers having a vinyl acetate content of &#x2267;40% by weight, where the compositions comprise a peroxide as crosslinking initiator. 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 of the invention, and also to the thermoplastic elastomers of the invention themselves and to their use for the production of mouldings.

Crosslinkable compositions based on polyamide and on &#x3b1;-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 &#x3b1;-olefin-vinyl acetate copolymers, where these compositions comprise a crosslinking initiator and the amount of polyamide in the compositions is &#x3c;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.
