摘要: 迄今为止,对四氢呋喃(THF)活性共聚合的研究报导甚少。THF均聚醚在分子量大于2000时易结晶使嵌段共聚产物性能变坏,因之THF活性共聚合的研究对嵌段共聚具有重要意义。

Abstract: The living chains were obtained in bulk tetrahydrofuran-propylene oxidc(PO) (10-20wt%) copolymerization initiated by adipoyl chloride(Ac-AgClO4, [Ac]0 = 0.02-0.09mol·l-1) catalyst at -10-0℃ without both chain termination and fransfer reactions.
