| 中文摘要 | Novel polyimide (PI) containing oxadiozole was synthesized via nucleophilic displacement polycondensation of dischlorophthalimide diphenyl ether with 2,5-bis(4-hydroxyphenyl)-1,3,4-oxadiozole. The study focused on the influence of the temperature, solvent and alkali on the polymerization. The results indicate that high molecular polymer with ηinh=0.50dL/g (NMP, 25℃) could be obtained in DMSO at 160℃ with KOH as the alkali. It was found that this kind of PI has better solubility and thermal property. Its glass transition temperature (Tg) is 217℃ and degradation temperature at 10％ (Td) is 460℃. |
