Abstract
Co-vulcanizates are produced from mixtures of (a) from 95 to 5% by weight of fluoroelastomers and (b) from 5 to 95% by weight of elastomers which contain nitrile groups and have from 25 to 140 nitrile-nitrogen atoms and less than 35 double bonds per 1000 carbon atoms, and (c) conventional mixture ingredients, the percentages relating to the sum total of (a) and (b). The co-vulcanizates are suitable for the production of seals and other rubber articles, in particular for areas of use which impose exacting requirements.
