Abstract
A composite rubber article is obtained by joining a rubber composition based on a brominated p-methylstyrene/isobutylene copolymer to a different material such as a plastic, inorganic and metallic material through a di-, tri- or tetra-alkoxysilane compound. The copolymer is firmly joined to the different material. The invention is applicable to the manufacture of composite rubber articles such as tires, high-pressure hoses, and pneumatic springs.
