Process for the preparation of plastoelastomeric compositions based on a thermoplastic olefinic polymer with an alkylphenol-formaldehydic resin and sodium bisulphite

摘要

Process for the preparation of plastoelastomeric preparations comprising an elastomeric phase of an EPDM elastomer and a plastomeric phase of a thermoplastic olefinic polymer, wherein the elastomeric phase is dynamically vulcanized with a vulcanizing binary agent consisting of an alkylphenol-formaldehydic resin and sodium bisulphite.
