单脒基铝络合物催化己内酯聚合及己内酯/丙交酯共聚被引量：6: 2011年; 将单脒基铝络合物用于催化ε-己内酯(ε-CL)开环聚合反应,结果表明,该类铝络合物表现出很高的催化活性:25oC时络合物[{PhC(N-2,6-iPr2C6H3)2}AlMe2](C1)催化ε-CL聚合1h,单体转化率为91%;70oC时络合物[{PhC(N-2,6-iPr2C6H3)-(N-2,6-Me2C6H3)}AlMe2](C2)催化ε-CL聚合15min,单体转化率达100%.脒基N-芳环上取代基的引入能明显提高催化剂活性,N-芳环邻位双取代的单脒基铝络合物的催化活性高于邻位单取代的.所得聚合物的分子量大于理论值,且分子量分布较宽(PDI=1.43～1.85),说明聚合的可控度不高.单脒基铝络合物可通过先催化ε-CL聚合,再引发外消旋丙交酯聚合,得到聚己内酯和聚丙交酯的两嵌段共聚物.; 钱峰刘克印马海燕; 关键词：Ε-己内酯开环聚合共聚
