ETHYLENE-TETRAFLUOROETHYLENE COPOLYMER MOLDING AND PROCESS FOR PRODUCING THE SAME

摘要

A process for producing an ethylene-tetrafluoroethylene copolymer molding, in which a high surface hydrophilization can be accomplished through simple productive operations; and a relevant ethylene-tetrafluoroethylene copolymer molding. An ethylene-tetrafluoroethylene copolymer molding is produced by providing a molding to be treated whose surface consists of a material composed mainly of an ethylene-tetrafluoroethylene copolymer and subjecting the surface to electric discharge treatment performed in a mixed gas containing oxygen and hydrocarbon under reduced pressure.
