Title: Gas separation membrane
Inventor: NISHI SHIRO
IPC: B01D71/64
Filed: 1990-01-22
Abstract: PURPOSE:To obtain a gas separation membrane having high gas permeation rate and excellent heat resistance by using fluorinated aromatic polyimide having a repeating structural unit expressed by a specified general formula. CONSTITUTION:Pyromellitic acid dianhydride and 2,2'-bis(trifluoromethyl)-4,4'- diaminobiphenyl are made into an equimolar reaction in a polar org. solvent (N,N-dimethylacetamide) to polymerize with polyamic acid, for which imide groups are added to obtain the polyimide having the repeating unit expressed by formula I. By fluorinating the polyimide, solubility and permeation coefft. can be increased. By introducing a trifluoromethyl group into the side chain, the diffusion constant is increased because of no interaction of molecules and the effect of steric hindrance. Thereby, this polyimide has higher permeability than an usual polyimide. Thus, the polyimide has a high gas permeation rate.
