COATED POLYOLEFIN

Patent ·
OSTI ID:4013630

A method is described for coating a surface of nonaromatic hydrocarbon polyolefin derived from mono-olefin monomers containing from 1 to 6 carbon atoms or a surface of copolymer of such non-aromatic hydrocarbon olefins with a chloroethylene polymer resin. The method consists of subjecting the surface to a field of at least 40000 r per hour of metal-penetrating, ionizing, high-energy radiation until the surface has received a dosage of at least 10 Mrad but less than that at which polymer degradation occurs. Subsequently a layer of a chloroethylene polymer resin is applied over the irradiated surface. The dosage is preferably less than 40 Mrad. The irradiated surface has a thickness between 0.5 and 5 mils and the chloroethylene polymer resin film has a thickness between 0.1 and 2.0 mils. The surface to be coated is either polybutylene, polyethylene, or polypropylene. The chloroethylene copolymer resin is comprised either of vinyl chloride and vinyl acetate, vinylidene chloride and vinyl chloride, vinylidene chloride and acrylonitrile, or vinylidene chloride and 1-2 carbon alkyl acrylate.
