HYDROGENATED NITRILE RUBBER CONTAINING PHOSPHINE SULFIDE OR DIPHOSPHINE SULFIDE

摘要

The invention relates to novel hydrogenated nitrile rubbers containing phosphine sulphides and/or diphosphate sulphides, to a process for production thereof, vulcanizable mixtures based on the hydrogenated nitrile rubbers, and to vulcanizates obtained in that way. The hydrogenated nitrile rubbers feature a very good profile of properties, especially with regard to the stress values at different elongations and the compression set after storage at high temperatures.

1. Hydrogenated nitrile rubbers comprising:
i) 0 to 1.0 wt % of phosphines, diphosphines or mixtures thereof based on the hydrogenated nitrite rubber, and ii) 0.075 to 10 wt % of phosphine sulphides, diphosphine sulphides or mixtures thereof based on the hydrogenated nitrile rubber.
