本文研究并比较了不同条件下新引发剂体系AlCl_3/SbCl_3/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。
In this paper, α-pinene polymerization products of new initiator system AlCl 3 / SbCl 3 / D (electron donor) under different conditions were studied and compared. The results show that the new initiator system can obtain the highest molecular weight and the narrower molecular weight distribution of the resin so far. The structural unit of the polymer molecular chain is different from the common initiator. Based on this, the hypothesis of the mechanism of cationic ring-opening polymerization was proposed.
