| Abstract: | 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. |
