PROCESS FOR THE PREPARATION OF POLYOLEFINIC PLASTO-ELASTOMERIC COMPOSITIONS BY MEANS OF DYNAMICAL VULCANIZATION

摘要

Preparation of plasto-elastomeric compositions endowed with an improved processability and consisting of a blend or mix of EPDM rubber cross-linked with a thermoplastic olefinic polymer, by means of dynamical vulcanization, using as a cross-linking agent for the rubber a halogen-donor free system consisting of a phenolic non-halogenated resin and a particular oxide or metal carbonate.
