| 摘 要： | 以三（3,5-二叔丁基水杨醛缩苯乙胺）镧La (OPEBS)3为引发剂引发L-丙交酯(L-LA)和ε-己内酯(ε-CL)的共聚，可控合成嵌段共聚物.研究了单体加料顺序、投料比、单体与引发剂的摩尔比(M/I)及聚合温度对L-LA和ε-CL共聚的影响.由石油醚抽提纯化的聚合物经GPC、1H NMR和DSC分析，表明该共聚物为L-LA和ε-CL嵌段共聚物.

| Abstract: | The ring-opening copolymerization of ：-LA and ε-CL using La（OPEBS）3 as the initiator is explored. The influences of monomer added order, monomer feeding ratio, the molar ratio of the monomer to initiator（M/D and the polymerization temperature on the copolymerization of L-LA and ε-CL have been investigated. The GPC, 1HNMR and DSC analysis of the product extracted by petroleum ether confirms that the product is the block copolymer. |
