Abstract

PURPOSE: To produce a high-molecular weight arom. polyester amide having excellent processability, by bringing an inert org. solvent phase contg. a specified phthalamide derivative and an arom. dicarboxylic acid dihalide into contact with an aq. phase contg. an acid acceptor to carry out a polycondensation reaction.
CONSTITUTION: A phthalamide derivative of formulaI(wherein R1, R4 are each a 1W3C lower alkyl; R2, R3 are each R1, Cl, Br), an arom. dicarboxylic acid dihalide of formula II (wherein X is Cl, Br; Ar is p- or m-phenylene, diphenylene, diphenylalkylene), and an arom. benzoyl halide of formula III are dissolved in an inert org. solvent to form an org. phase to which is then added an aq. phase contg. an acid acceptor such as NaOH and an inorg. salt electrolyte such as NaCl. The mixture is subjected to a polycondensation reaction at -10W40°C for 2W4hr to produce an arom. polyester amide of formula IV (wherein n≥5) having a softening temp. of 270W320°C, a heat decomposition temp. ≥400°C and a reduced viscosity ≥0.8.
