Abstract
Abstract IN WHICH X represents a hydrogen atom or a methyl group and Y represents an organic group containing up to eight carbon atoms and at least one carbon-fluorine bond. A film comprising said compound is applied to an exterior surface of the elastomer substrate and polymerized thereon with a beam of electrons having average potential below about 300,000 volts, preferably below 260,000 volts. An article of manufacture of unique surface properties is produced from an elastomer substrate and a compound represented by the formula
