ABSTRACT:
An improved double-layered rubber laminate is proposed, which is an integral body consisting of a first layer of an organopolysiloxane-based rubber composition and a second layer of an acrylic rubber-based composition. When the acrylic rubber in the latter composition is not a conventional acrylic rubber but a copolymeric rubber of a (meth)acrylate ester monomer and an organosilicon monomer having, in a molecule, at least one silicon-bonded vinyl group and an ethylenically unsaturated group other than silicon-bonded vinyl groups, such as 3-methacryloxypropyl, very firm bonding can be obtained between the layers by the co-vulcanization of the laminated layers to exhibit very high resistance against delamination.
