Improved hydrogenated nitrile rubber laminates.

摘要

A process is provided for improving in an at least two layer laminate the adhesion of a first rubbery layer containing hydrogenated butadiene-acrylonitrile polymer to a second rubbery layer containing one of butadiene-acrylonitrile rubber, hydrogenated butadiene-acrylonitrile polymer or fluoroelastomer polymer by incorporating into said first rubbery layer an adhesion improving compound selected from bis[alkoxysilyl-alkyl]-tetrasulphides and bis[alkoxysilyl-aryl]-tetrasulphides.
