Abstract

PURPOSE: To obtain a selective permeable membrane for separation of gases, having excellent selective permeability and excellent durability, from the copolymer of vinyl pyridine with an acrylate or methacrylate as a raw material.
CONSTITUTION: A vinyl pyridine having a repeating unit of the formula [I], e.g., 2-vinyl pyridine, 4-vinyl pyridine, etc., and an acrylate or methacrylate having a repeating unit of the formula [II] (where R1 is H or methyl group and R2 is a C1W30 straight or branched chain alkyl group) are subjected to copolymerization, e.g., radical polymerization, anionic polymerization, etc., in a proportion of 5:95W95:5, and then the liquid copolymer thus obtained is molded into a 0.01W500μ thickness membrane by extrusion molding method, etc. Thus, a permeable membrane having excellent permeability and excellent durability, which can be used for preparing oxygen-enriched air from air or separating He gas from natural gas, etc., can be obtained.
