| 摘 要： | 利用配体(2-MeO-C6H4N=C(Me) CHC=C(Me)=NH-2-MeO-C6H4)和三烷基钇(Y(CH2SiMe3)3THF2)在低温下反应,合成了一种新型配合物.这种配合物对外消旋丙交酯(rac-LA)开环聚合反应具有很高的活性,并且生成的聚乳酸(PLA)的分子量分布比较窄.经实验证明,配合物的双烷基都参与引发单体聚合的反应,该聚合反应是活性聚合.

| Abstract: | By using the reaction of ligand(2-MeO-C 6H 4N=C(Me) CHC=C(Me) =NH-2-MeO-C 6H 4) and Three alkyl yttrium(Y yttrium alkyl(CH 2SiMe 3) 3THF 2) at low temperature,a novel complex comes into being.Such complexes have a high activity for racemic lactide(rac-LA) ring opening polymerization reaction,and generate the polylactic acid(PLA) that owns relatively narrow molecular weight distribution.Experiments prove that double alkyl complexes are involved in triggering monomer polymerization,the polymerization reaction is active polymerization. |
