ABSTRACT:
The present application provides novel nitrile rubbers comprising repeating units of at least one α,β-unsaturated nitrile, at least one conjugated diene and optionally one or more further copolymerizable monomers which nitrile rubbers are distinguished by a specific calcium content as well as a specific chlorine content and dispose of specific thio end groups. Additionally, an improved polymerization and work-up process is provided to produce the aforementioned nitrile rubbers.
