本实验室前项工作曾证明用脂肪二酰氯与高氯酸银引发四氢呋喃(THF)在0—50℃下聚合可形成没有链终止和链转移反应的活性聚合链.为了减少聚丁二醇醚结晶趋势,又制备了双端活性的THF-环氧丙烷无规共聚醚链.本文则通过THF的开环聚合,将一个非“活性”的聚酯转变成为双端活性链,合成了伯胺端基聚丁二醇-聚酯-聚丁二醇遥爪低聚物,并用以增韧环氧树脂.
The previous work in this lab has demonstrated that the polymerization of tetrahydrofuran (THF) with fatty diacid and silver perchlorate at 0-50 ° C proves to form an active polymeric chain free of chain termination and chain transfer reactions.In order to reduce polybutylene glycol ether Crystallization trend, but also prepared a double-terminal activity of THF-propylene oxide random copolyether chain.In this paper, through the ring-opening polymerization of THF, a non-active polyester into a double-ended active chain synthesis of primary amine End-group polybutylene glycol-polyester-polybutylene telechelic oligomers and toughening epoxy resins.
