Oxygen permeable polymer molded body

Abstract

Abstract PURPOSE:To obtain an oxygen permeable polymer molded body excellent in a film forming property, having large transmission coefficient and high in a transmission coefficient ratio of oxygen and nitrogen, by using a polymer or a copolymer of fumaric diester prepared by radial polymerization. CONSTITUTION:A polymer, which is obtained by the radical polymerization of isopropyl alkyl fumarate represented by formula I (wherein R is an 1-12C alkyl group or a 3-12C cycloalkyl group) or radical copolymerization of said fumarate and a vinyl compound having a polymerizable double bond in the molecule thereof, is used. It is necessary to contain fumaric diester in an amount of 80wt% or more and the number average MW of the polymer is pref. about 8,000-300,000. In use, this polymer is formed into a membrane with a thickness of 0.01-200mum. The oxygen transmission coefficient of this membrane is 10<-9>cm<3> cm/cm<2>.sec.cm.Hg and a transmission coefficient ratio of oxygen and nitrogen is 2.7 or more.
