Phenylacetylene was polymerized with WOCl,/tetraphenyltin (mole ratio 1 : 2) catalyst in benzene and benzene/ 1 ,4-dioxane mixtures. The resulting polymers were characterized by means of multidetector size-exclusion chromatography and ' H NMR and IR spectroscopy. 1,4-Dioxane used as a co-solvent was
