Problems solved by technology

However, a disadvantage is the need to perform an additional reaction step which consumes an additional expensive catalyst and leads to changes in the polymer chain
[0023] Therefore, the known production methods and the hydrogenated nitrile rubbers produced therefrom are not yet satisfactory for further processing and certain applications

Abstract

The present invention relates to a process for producing PEG acrylate-HNBR copolymer which exhibits excellent processability by latex hydrogenation of PEG acrylate-NBR latex to afford PEG acrylate-HNBR latex and subsequent coagulation.

Description

technical field [0001] The present invention relates to a process for producing PEG acrylate-HNBR copolymers exhibiting excellent processability by latex hydrogenation of PEG acrylate-NBR latex to provide PEG acrylate-HNBR latex and subsequent coagulation. Background technique [0002] The rubber industry is constantly searching for improved synthetic rubbers that meet the increasing demands of customers. Nitrile rubber, especially hydrogenated nitrile rubber, plays an important role. [0003] Nitrile-butadiene rubber ("NBR"; nitrile-butadiene rubber copolymer) is understood to mean a rubber which is at least one α,β-unsaturated nitrile, at least one conjugated diene and optionally one or more Copolymers or terpolymers of additional copolymerizable monomers. Hydrogenated nitrile rubbers (“HNBR”) are understood to mean corresponding nitrile rubbers in which the C═C double bonds of the incorporated diene units have been optionally fully or partially hydrogenated.
