Abstract
PURPOSE:To obtain an oxygen permselective membrane having high efficiency by carrying out emulsion polymn. of a monomer such as alkyl ester of alpha,beta- ethylenic unsatd. carboxylic acid, etc., with a monomer contg. an unsatd. double bond and an alkoxysilyl group, and colloidal silica. CONSTITUTION:A kind of monomer (a) among alkyl esters of alpha,beta-unsatd. carboxylic acid such as 2-hexyl acrylate, methyl methacrylate, etc., and alkyl benzene such as styrene, etc., is mixed with a monomer (b) contg. an unsatd. double bond and an alkoxysilyl group such as gamma-methacryloyloxypropyl trimethoxysilane, etc., and colloidal silica (c) in 100:(0.1-10):(1-200) proportion, and an aq. dispersion of resin is obtd. by carrying out emulsion polymn. of the monomers in the presence of an anionic or nonionic surface active agent. The aq. dispersion is formed to film by flowing on a surface. Obtd. film has high O2 permselectivity and high tensile strength.
