Copolymers of phenylacetylene (PA) and p-nitrophenylacetylene (pNPA) with various monomers ratios were prepared and characterized. The solubility of copolymers is dependent on the number of PA units in the chain. They show a good degree of stereoregularity and the M W s are in the 10 3 -10 5 a.m.u.
Copolymers of p-diethynylbenzene with phenylacetylene in the presence of cobalt-tri-nbutylphosphine in diethylamine at room temperature with high molecular weight were synthesized. The copolymers, having the advantage of being highly soluble in common organic solvents, possess mainly trans p-conjuga
