PHENOL-CONTAINING HYDROGENATED NITRILE RUBBER

摘要

Novel hydrogenated nitrile rubbers having a specific phenol content are provided, as are a process for production thereof, vulcanizable mixtures based thereon and vulcanizates thus obtained. The vulcanizates feature particularly good moduli and compression set values, and very good storage stabilities.

1. Hydrogenated nitrile rubber comprising 0.01 wt % to less than 0.45 wt % of at least one substituted phenol of the general formula (I) based in each case on the hydrogenated nitrile rubber, in which
R1, R2, R3, R4 and R5 are the same or different and are each hydrogen, hydroxyl, a linear, branched, cyclic or aromatic hydrocarbyl radical having 1 to 8 carbon atoms and additionally one, two or three heteroatoms, where at least one of the R1, R2, R3, R4 and R5 radicals is not hydrogen.
