• The conditions for condensation-polymerization of olygomer which was prepared from Bisphenol A and phosgene by the addition of caustic soda have been investigated. The results indicated that the molecular weight of polymer can be adjusted to any desired extent by addition of a small amount of monohydric alcohols or phenols. Also, the rate of formation of polymer was increased by vigorous agitation, raising temperature and increasing concentrations of olygomer and caustic soda. Addition of methanol and catalyst was effective to complete condensationpolymerization reaction, and separation into two layers after the reaction and the removal of salt as the by-product be came easy . Vigorous stirring and increasing the concentration of catalyst resulted in the increase of the molecular weight of the polymer .
