Production of selective separating membrane element for gas

Abstract

Abstract PURPOSE:To obtain a titled element having good selective separability and a sufficient rate of air permeation by allowing a specific material to exist in producing the separating element by graft polymerizing silicone with a fluoropolymer. CONSTITUTION:A fluoropolymer and silicone are brought into graft reaction in the presence of silane having reactivity in the stage of bonding chemically both components to each other by polymer reaction to form a graft polymer thereby, synthesizing a selective separating element for gas. The formation of the separated phase structure consisting of both components into a microstructure is thus made possible and the purposes are achieved.
