Abstract

The invention relates to vulcanizable compositions based on carboxylated nitrile rubbers, at least one resol crosslinker, at least one silicatic filler and at least one specific silane, to a process for preparing these vulcanizable compositions, to a process for producing vulcanizates therefrom and to the vulcanizates thus obtained. The vulcanizates feature good mechanical and dynamic properties and an excellent compression set.
