after phenylacetylene is polymerized at 150 ℃ for 12h in nitrogen, the obtained polymer is heated for 6h at different temperatures and 27.58 × 10Pa. when the temperature rises, the polymer becomes highly crystalline. the unpaired electron spin concentration and conductivity increase with the temperature, and at 600 ℃, the maximum value is (2.3 × 1020 spin/g), but suddenly decreases above 700 ℃. Polymerization of phenylacetylene in the presence of a catalyst, heating 150-200°C, protection in nitrogen, polymerization reaction to obtain black-brown polyphenylacetylene, such as polymerization in toluene, chlorobenzene, olefin solution, the yield is 20%, according to the synthesis of different temperatures of polyphenylacetylene is yellow-black powder, the molecular weight is between 500-1000.
