Abstract
p-Diethynylbenzene was polymerized in the presence of cobalt-phosphine in diethylamine at room temperature. The polymer had a molecular weight of ∼13000 and the yield was 73.1–73.6% (M/Cat.=100; for 10 h at 25°C). The polymers, highly soluble in polar organic solvents, possess the main chain containing π-conjugated linear polyene and the side chains consisting of the p-ethynylphenylene pendant groups. The effect of concentration and reaction time on the yield and product solubility were investigated.
