Abstract
PURPOSE: To form a gas separation film with excellent chemical resistance, heat resistance and oil resistance of which both separation coefficient and a permeation coefficient and a permeation speed of oxygen and nitrogen are high by subjecting an organopolysiloxane and a fluorine containing polymer to graft copolymerization.
CONSTITUTION: 15g fluorine containing polymer segment of which an average polymerization degree is 800 and a molar ratio of C2F2/C3H6/glycidyl vinyl ether is 54/44/2 and 5g amino group containing organopolysiloxane of which a polymerization degree is about 5,000 are dissolved in trifluorotrichloroethane and the resulting solution is stirred for about 2hr. After stirring, the temp. thereof is lowered to 47°C and, while the solvent is volatilized, the reaction is carried out for one hr and said reactants are further heated to 80°C to be reacted for 1.5hr under vacuum. When the obtained polymer is dissolved in ethyl acetate and the resulting solution is coated on a glass plate and dried in air or under vacuum, a film with a thickness of 9.4μ is obtained. The separation coefficient of this film (PO2/PN2) is 3.29.
