以有机锌化合物为引发剂，进行了N-苯基马来酰亚胺（N-PMI）的聚合反应。在所考察的引发剂中，[Zn（OCH 3）2·（C2 H5 ZnOCH 3）6]的聚（N-PMI）产率最高。聚合物产率在聚合反应的早期阶段迅速增加。所产生的聚（N-PMI）在GPC中显示出在高分子量区域中的单峰分子量分布和在低聚物区域中的两个组分。1H NMR和13 C NMR谱表明加成聚合没有任何明显的副反应。与苯乙烯的共聚和在硝基苯中的聚合的结果表明离子聚合机理。
The polymerization of N-phenylmaleimide (N-PMI) was carried out with organozinc compounds as initiators. Within the initiators examined [Zn(OCH3)2·(C2H5ZnOCH3)6] gave the highest yield of poly(N-PMI). The polymer yield increased rapidly at the early stage of the polymerization reaction. The poly(N-PMI) produced shows a unimodal molecular weight distribution in the high-molecular-weight region and two components in the oligomeric region in GPC. 1H NMR and 13C NMR spectra suggest an addition polymerization without any remarkable side reactions. The results of the copolymerization with styrene and of the polymerization in nitrobenzene suggest an ionic polymerization mechanism.
