| Abstract: | A polyester containing diacetylenic units in main chain was prepared by the polycondensation of m, m -butadiynylene dibenzyl alcohol with terephthaloyl chloride. The polymer was crystalline, and bearly soluble in hot dimethylformamide or dimethylsulfoxide, but insoluble in most organic solvents. It melts at about 200°C. Irradiation of UV light at 75°C gave a reddish brown resin. Heating at temperatures above its melting point gave a shinning black hard solid. |
