| 英文摘要 | the gas permeation behavior of 2,2'-bis(3,4'dicarboxyphenyl) hexafluoropropane dianhydride(6fda)-2,4,6-trimetllyl-1,3-phenylenediamine (tmpda)/4,4'-methylene bis(2-chloroaniline) (moca) copolyimides was investigated by systematically varying the diamine ratios. all the copolyimides were soluble in most of the common solvents. the gas permeabilities and diffusion coefficients decreased with increasing moca content; however, the permselectivity of gas pairs such as h-2/n-2, o-2/n-2, co2/ch4 was enhanced with the incorporation of moca moiety. moreover, all of the copolyimides studied in this work exhibited performance near, lying on or above the existing upper bound trade-off line between permselectivity and permeability.
