- W2783609424 abstract "合成了一系列非对称 β -二亚氨基镁硅氨基络合物，通过 1 H NMR、 13 C NMR和元素分析进行了表征，典型络合物经X-射线单晶衍射确定了其晶体结构.利用上述镁络合物在四氢呋喃中催化外消旋丙交酯开环聚合主要得到较低至中等杂规度的聚合物（ P r =0.64~0.80）.镁络合物在室温、甲苯中对 e -己内酯开环聚合表现出中等的催化活性，得到较宽分子量分布的聚合物（ M w / M n =1.37~1.67）.利用典型镁络合物 2 进行催化 L -丙交酯和 e -己内酯共聚的研究，采用分步加料法（两种不同加料顺序）以及一锅法均得到了两嵌段结构为主的共聚物.所得共聚物通过核磁氢谱、碳谱等测试，进一步确定了其微观链结构." @default.
