Abstract
PURPOSE: To prepare a polyester copolymer having high glass transition temperature and excellent mechanical properties and moldability, by using a dicarboxybenzanilide or its derivative as a part of acid component, and an alkylene glycol.
CONSTITUTION: The title polyester is prepared by the polycondensation of (A) an acid component composed of (i) terephthalic acid or its derivative and (ii) a 4,4'-dicarboxybenzanilide derivative of formula (R1,2 are H, lower alkyl, or phenyl) and (B) a 2W4C alkylene glycol. The amount of the (ii) component is 0.5W 50mol%, pref. 2W40mol%, based on the (A) component. The (ii) component can be prepared, e.g. by reacting a p-aminobenzoic acid ester with equimolar amount of the acid chloride of a terephthalic acid monoester.
