摘要
用四苯基卟啉氯化铝活性开环催化剂进行ε－己内酯（ＣＬ）和环氧丙烷（ＰＯ）嵌段共聚合，制备了ＰＣＬ－ＰＰＯ、ＰＰＯ－ＰＣＬ以及ＰＣＬ－ＰＰＯ－ＰＣＬ、ＰＰＯ－ＰＣＬ－ＰＰＯ嵌段共聚体。
The ring opening living polymerization of caprolactone(CL) or propylene oxide(PO) was carried out using tetraphenyl porphyrin aluminium cnloride(TPPAL-Cl) as catalyst in toluene at 20～80℃.The polymerization was shown in characters of living polymerization with the linear relationship of and conversion.The block copolymers of PCL-PPO,PCL-PPO-PCL and PPO-PCL-PPO were prepared and characterized.
