Process for the production of water and solvent-free hydrogenated nitrile rubbers

摘要

The present invention relates to a process for the production of water and solvent-free hydrogenated nitrile rubber polymers, to the hydrogenated nitrile rubbers and the use thereof. The hydrogenetaed nitrile rubbers comprise repeating units derived from at leat one conjugated diene, at least ±, ²-unsaturated nitrile and optionally one or more copolymerizable monomers and having a viscosity of at maxium 20.000 Pa*s (measured at 100ºC and at a shear rate of 1/s), preferably at maxium 10.000 Pa*s, more preferably at maximum 5.000 Pa*s and most preferably at maximum 1.000 Pa*s.
