The Polymerization of acetylenes have been extensively studied

for the polymers obtained are a kind of prospective material of organic conductor and semiconductor.We Found that in the presence of molybdenum complexes

propargyl alcohol and propargyl chloride copolymerized with vigorous reactions. We obtained polymer Ⅰ insoluble in all solvents studied

and polymer Ⅱ

solubel in methanol

chloroform

acetone etc.

with molecular weight 700-1000.We have tried using 9 complexes of Ti

Zr

Fe

Co

Ni as catalyst

but no reaction has taken place.
