Abstract
This invention is concerned with a process for the surface treatment of a rubber containing ethylenic unsaturation by coating the rubber with an alkyl halide and exposing the thus coated rubber surface to ultraviolet-visible light. Such modification produces a rubber article having reduced air permeability, enhanced ozone protection and improved release properties.
