Gas separating membrane material

Abstract

Abstract PURPOSE:To obtain the titled material having a separation coefficient well- balanced with a transmission velocity of oxygen and the durable stability of quality by using a copolymer of fluorinated olefin and trialkylsilanoylvinyl ether. CONSTITUTION:A copolymer composed of 5-60mol% fluorinated olefin and 50- 5mol% trialkylsilanoylvinyl ether is suitably used. A polymer contg. the third component such as <=45% alpha-olefin, alkylvinyl ether or vinyl ester is also appropriately used. Solution polymn. and bulk polymn., and emulsion polymn., radiation polymn. or plasma polymn. can also be used. 10<3>-10<6> mean molecular weight is generally adopted, and a thin film as a separation element having 100Angstrom -100mu thickness is suitably formed. As a molding means, cast molding etc. is preferably used.
