Abstract
Plasto-elastomeric compositions with improved processability and high elasto-mechanical properties, consisting of mixes of a cross-linked EPDM rubber and a thermoplastic olefinic polymer, are prepared by the dynamic vulcanization method, using as cross-linking agent for the rubbery component a system comprising a non-halogenated phenolic resin, zinc oxide and p-toluenesulfonic acid.
