| 英文摘要 | 4,4'-bis(3,4-dicarboxyphenylthio)diphenyl sulfone dianhydride(4,4'-ptpsda) and 4,4'-bis(2,3-dicarboxyphenylthio)diphenyl sulfone dianhydride(3,3'-ptpsda) were synthesized from chlorophthalic anhydrides and bis(4-mercaptophenyl)sulfone. their structures were determined via ir spectra, h-1 nmr and elemental analysis. a series of polyimides were prepared from isomeric ptpsdas and aromatic diamines in 1-methyl-2-pyrrolidinone (nmp) via the conventional two-step method. polyimides based on 4,4'-ptpsda and 3.3'-ptpsda have good solubility in polar aprotic solvents and phenols. the 5% weight-loss temperatures of isomeric polyimides were near 500 degrees c in n-2. dmta and dsc analyses indicated that the glass-transition temperatures of polyimides front 3,3'-ptpsda are higher than those of polyimides from 4,4'-ptpsda. the wide-angle x-ray diffraction showed that all polyimides are amorphous. the polyimides from 3,3'ptpsda showed higher permeability but lower permselectivity compared with those from 4.4'-ptpsda.
