| 摘 要： | Soluble polyacetylene (PA) with well--defined nature has been synthesized with catalyst system Nd(i-OPr)_3/AIR_3 (R=C_2H_5-, i-C_4H_9-) and characterized by IR, Raman and ESR Spectra etc. Number average molecular weight of the soluble specimen were determined by VPO to be about 500g/mol. or lower. The IR and NMR spectra and end group analysis of" the soluble polyacetylene fully demonstrate that polymerization of acetylene with rare-earth catalyst is realized through monomer insertion between the transition metal-carbon bond.
