中文摘要：
分别采用三氯化镧和三氯化铈为主催化剂，以正丁基锂（n—BuLi）为助催化剂，分别在DMF和乙醇溶剂中探讨了苯乙炔的聚合研究，考察了聚合温度、Li／La、Li／Ce摩尔比等因素对聚合反应的影响。结果表明，三氯化镧／正丁基锂和三氯化铈／正丁基锂体系催化苯乙炔聚合显示了一定的催化活性。除含羧基乙炔单体外，LaCl3／n—Bu—Li和CeCl3／n—BuLi催化体系对极性乙炔衍生物单体同样也具有一定催化活性。
英文摘要：
Polymerization of phenylacetylene in DMF and EtOH were catalyzed by Lanthanum chloride/n - BuLi and Cerium chloride/n - BuLi catalytic systems, respectively. The influences of polymerization conditions such as polymerization temperature and Li/La or Li/Ce molar ratio were investigated. The obtained polymer was characterized by proton nuclear magnetic resonance, Fourier - transform infrared spectroscopy, and wide - angle X - ray diffrac- tion. The Lanthanum chloride/n -BuLi and Cerium chloride/n -BuLi catalytic systems exhibited definite catalytic activity, but have activity for polar acetylene derivatives.
