Abstract

PURPOSE: To facilitate the control of polymerization degree and to produce a high-MW aromatic polyester-amide, by contacting an acid acceptor-containing aqueous phase with an organic phase prepared by dissolving a specified benzoyl halide in an inert organic solvent.
CONSTITUTION: (Hydroxyphenyl)(aminophenyl)propane is reacted with at least 2 molar time aromatic dicarboxylic acid dihalide at -10W40°C for 5W10min in an inert organic solvent to form a benzoyl halide of formulaI, wherein R1 and R4 are each H or a 1W3C lower alkyl, R2 and R3 are each R1, Cl or Br and X is Cl or Br. Next, to an organic phase prepared by dissolving said benzoyl halide in an inert organic solvent is added an aqueous phase containing an acid acceptor, e.g., NaOH, and an inorganic electrolyte, e.g., NaCl, and the mixture is polycondensed at -10W40°C for 2W4hr to obtain an aromatic polyester-amide of formula II, wherein n≥15, having a softening point of 270W320°C and a thermal decomposition temperature ≥400°C.
