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,LaCl_3/n-BuLi和CeCl_3/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.

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 diffraction. The Lanthanum chloride/n-BuLi and Cerium chloride/n-BuLi catalytic systems exhibited definite catalytic activity,but have activity for polar acetylene derivatives.
