Abstract

A process for bonding a polyamide containing thermoplastic material and a rubber, comprising covulcanizing, in the presence of a vulcanization system, a thermoplastic component which contains at least 30% by wt. of an aliphatic polyamide and a rubber composition which, based on 100 parts by weight of a carboxyl group-containing rubber, contains 100-300 parts by wt. of fillers, and 1-10 parts by wt. of peroxidic vulcanizing agents.
