dc.descriptionFrom the diphenol N-(2,6-diiodo-4-nitrophenyl)-3,3-bis(4-hydroxyphenyl)-butanamide, the synthesis of the poly(carbonate) with phosgene, the poly(thiocarbonate) with thiophosgene and the poly(ester)s with adipoyl chloride, isophthaloyl chloride and terephthaloyl chloride are described under phase transfer conditions using several quaternary ammonium salts as catalysts. The bahaviour of the catalysts was evaluated by the yields and the inherent viscosity values, comparing them with those obtained without catalyst. In general the phase transfer process was effective in all cases observing an increase of both parameters. All the polymers were insoluble in the reaction media which limited the growth of the polymeric chains
