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。
Rod-coil diblock copolymers of PPQ-b-PEG containing poly(phenylquinoline) (PPQ) as the rod block and the poly(eth-ylene glycol) (PEG) as the coil block were designed and synthesized from Methyl-PEG(Mw : 2000), butanedioic anydride 4-Aminoaceto-phenone, 5-aceryl-2-aminobenzophenone. The structures of PPQ-b-PEG are characterized by IR, 1HNMR. And thermostabilities are studied. The results show that the first decomposition temperature of PPQ-b-PEG is 250°C. The weight of PPQ-b-PEG is reduced by 5% at 250-400°C. It is reduced rapidly at 400-600°C.
