摘要

Soluble polyacetylene (PA) with well--defined nature has been synthesized with catalyst system Nd(i-OPr)3/AIR3 (R=C2H5-

i-C4H9-) 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.

Soluble polyacetylene (PA) with well--defined nature has been synthesized with catalyst system Nd(i-OPr)3/AIR3 (R=C2H5-
