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.
Claims14
A process for producing a PEG acrylate-HNBR copolymer,
- comprising subjecting a PEG acrylate-NBR latex to a hydrogenation and subsequently a coagulation, wherein the PEG acrylate-NBR latex contains
- (a) 10% to 60% by weight of at least one α,β-ethylenically unsaturated nitrile unit,
- (b) 20% to 80% by weight of at least one conjugated diene unit, and
- (c) 10% to 60% by weight of a PEG acrylate unit derived from a PEG acrylate of general formula (I)
- based on the total amount of monomer units,
- wherein
- R is hydrogen or branched or unbranched C1-C20-alkyl
- n is 1 to 8, and
- R1 is hydrogen or methyl.
