摘　　要：A new kind of catalyst WOBr_4,which can be used in the polymerization of phenylacetylene(PhA),has been synthesized.The obtained polyphenylcetylene(PPhA) using WOBr_4 as catalyst is soluble、fusible、with brown-red colour and has 1831(M n).The analysis of the stucture of PPhA shows that the polymer has cis-transoidal structure,therefore,the reaction mechanism is via complex catalysis.A new kind of catalyst WOBr_4,which can be used in the polymerization of phenylacetylene(PhA),has been synthesized.The obtained polyphenylcetylene(PPhA) using WOBr_4 as catalyst is soluble、fusible、with brown-red colour and has 1831(M n).The analysis of the stucture of PPhA shows that the polymer has cis-transoidal structure,therefore,the reaction mechanism is via complex catalysis.
