ABSTRACT:
This invention is directed to a method, a rubber skim stock and a product containing the skim stock having improved adhesion between a metal member and contiguous rubber skim stock. The invention lies in the discovery that improved rubber-to-metal adhesion can be obtained by adding to an otherwise conventional rubber skim stock composition appropriate amounts of a tetracarboxylic dianhydride.
The method of this invention comprises the steps of mixing a tetracarboxylic dianhydride into a rubber composition, bringing this composition into contiguous relationship with a metal member in an unvulcanized product and vulcanizing the product to yield the end product.
