Abstract

Co-vulcanizates having good mechanical properties are obtained from mixtures of: (a) from 35 to 5%, by weight, of hydrocarbon elastomers; (b) from 65 to 95%, by weight, of nitrile group-containing elastomers having from 25 to 140 nitrile nitrogen atoms and less 12 double bonds per 1000 carbon atoms; by radical cross-linking.
