Polymeric compositions suitable for the manufacture of foamed articles, and a process for preparing the same.

摘要

Polymeric compositions suitable for the manufacture of foamed articles, comprising a foaming agent in admixture with a dynamically vulcanized mix of an EPDM rubber or of an ethylene-propylene elastomeric copolymer with a thermoplastics olefinic polymer. A process for preparing such compositions comprises the steps of dynamically vulcanizing a mix of EPDM rubber or of an ethylene/propylene elastomeric copolymer with a thermoplastics olefinic polymer and successively mixing the mix with a foaming agent, at low temperature.
