Abstract

A process for bonding a thermoplastic PPE-containing polymer and a rubber by covulcanization, comprising the steps of: PA1 heating and covulcanizing said PPE-containing polymer and said rubber, wherein said rubber comprises: PA1 (a) 100 parts by weight of a mixture comprising 100-20 wt. % of an EP(D)M rubber and 0-80 wt. % of a styrene-butadiene rubber obtained by emulsion polymerization, PA1 (b) 100-300 parts by weight of loading material, PA1 (c) 1-10 parts by weight of a peroxidic vulcanization agent, and PA1 (d) 0.5-4 parts by weight of a vulcanization activator, wherein a vulcanization bond is formed between said PPE-containing thermoplastic polymer and said rubber.
