摘要： Provided are new partially hydrogenated nitrile rubbers which are distinguished by a specific ratio of viscosity to molecular weight, and also vulcanizable mixtures and vulcanizates based on said rubbers, and also the associated preparation processes. The partially hydrogenated nitrile rubbers lead to compounded formulations having advantageous processing properties in conjunction with excellent vulcanizate properties.
