| 摘要: |
| 以聚乙二醇单甲醚、丁二酸酐、4-氨基苯乙酮、5-乙酰基-2-氨基二苯甲酮为原料合成了以聚苯基喹啉(PPQ)为硬段、聚乙二醇(PEG)为软段的“刚棒—线团”两嵌段共聚物PPQ-b-PEG，通过IR、1HNMR对其结构进行了表征，并对PPQ-b-PEG嵌段共聚物的热稳定性进行研究，结果表明：PPQ-b-PEG(d)的热稳定性高，PPQ-b-PEG起始的分解温度为250℃，在250～400℃失重很少，其失重率小于5%，在400～600℃才迅速失重，到620℃时彻底分解。 |

| Abstract: |
| Rod-coil diblock copolymers of PPQ-b-PEG containing poly(phenylquinoline) (PPQ) as the rod block and the poly(ethylene glycol) (PEG) as the coil block were designed and synthesized from Methyl-PEG(Mw:2000), butanedioic anydride 4-Aminoacetophenone, 5-acetyl-2-aminobenzophenone. The structures of PPQ-b-PEG are characterized by IR, 1HNMR. And thermostabilities are studied.The results show that the first decompostion temperature of PPQ-b-PEG is 250℃.The weight of PPQ-b-PEG is reduced by 5% at 250～400℃. It is reduced rapidly at 400～600 ℃. |
