Ring-opening copolymerization of L-LA and ε-CL initiated by the Lanthanum Tris(N-phenylethyl-3, 5-di-t-butylsalicylaldiminato)s(三（3，5-二叔丁基水杨醛缩苯乙胺）镧引发L-丙交酯与ε-己内酯开环共聚合)

Ring-opening copolymerization of L-LA and ε-CL initiated by the Lanthanum Tris(N-phenylethyl-3, 5-di-t-butylsalicylaldiminato)s(三（3，5-二叔丁基水杨醛缩苯乙胺）镧引发L-丙交酯与ε-己内酯开环共聚合)

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....
