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 hydrogenated nitrile rubbers comprise repeating units derived from at least one conjugated diene, at least one alpha, beta - unsaturated nitrile and optionally one or more copolymerizable monomers and having a viscosity of at maximum 20000 Pa*s (measured at 100 degrees Celsius and at a shear rate of 1/s), preferably at maximum 10000 Pa*s, more preferably at maximum 5000 Pa*s and most preferably at maximum 1000 Pa*s.
