Abstract
PURPOSE:To obtain the title cpd. having excellent moldability, heat resistance and mechanical strengths, comprising a specific arom. dihydroxy cpd., an arom. dicarboxylic acid cpd. (or its salt) and, if necessary, an arom. hydroxycarboxylic acid cpd. CONSTITUTION:A wholly arom. polyester cpd. whose average MW is 2,000-50,000 is obtd. by heating an arom. dihydroxy cpd. represented by formula I or II (wherein R is lower alkyl or lower alkoxy; n is 0-3), equimolar arom. dicarboxylic acid cpd. (or its salt) (e.g., isophthalic acid) and, if necessary, an arom. hydroxycarboxylic acid cpd. (e.g., resorcinol) in the presence of acetic anhydride to acetylate the hydroxyl groups and thereafter carrying out polycondensation reaction at 200-350 deg.C while removing produced acetic acid.
