摘要： 本文研究并比较了不同条件下新引发剂体系AlCl3/SbCl3/D(电子给体)的α-蒎烯聚合产物。结果表明,该新引发体系可获得迄今分子量最高、分子量分布较窄的树脂;聚合物分子链结构单元与常用引发剂的不同。据此本文提出了正离子开环聚合作用机理的假设。

Abstract: The characteristic of polymerization of a-pinene initiated by a new initiating system AlCl3/SbCl3/Donor was studied by several spectroscopies, and they were compared with that obtained under the varied polymerization conditions. The results indicate that the product with a high molecular weight is obtained with different molecular structure units. According to the experimental data, the ring-opening polymerization mechanism of a-pinene polymerization initiated with this system is put forward.
