ABSTRACT:
A method for the surface treatment of rubber, a process for production of a rubber article, and a rubber composition wherein a structure derived from a fluorine compound containing a fluoroalkyl at both ends of its molecule are joined to a polymer main chain of crosslinked rubber in the vicinity of the surface of a rubber base (molding). The method involves causing the fluorine compound and a silane coupling agent to exist in the vicinity of the surface of a rubber base, and heat-treating the rubber base. The production process comprises compounding and mixing raw rubber and a silane coupling agent to obtaining a molding of crosslinked rubber and heating the molding. The rubber composition contains raw rubber, a crosslinking agent, the fluorine compound and a silane coupling agent.
