Abstract: 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° C., and also oil resistance. They can be used for production of moldings.

Abstract: Crosslinkable compositions based on at least one copolyester as thermoplastic elastomer and on ?-olefin-vinyl acetate copolymers having a vinyl acetate content of ?40% by weight, where the compositions comprise a peroxide as crosslinking initiator.

Abstract: A vulcanizable composition based on ethylene-vinyl acetate copolymers is prepared with vinyl acetate content of at least 45% by weight, based on the copolymer, and these can be crosslinked in the absence of peroxides. These mixtures comprise at least one organotin catalyst and a specific crosslinking agent. A process is moreover described for preparation of these vulcanizable compositions, and their use is described for production of products with elastomeric properties.
