Abstract

PURPOSE: To prepare a polyamide-imide resin having excellent electrical properties, heat resistance, and mechanical properties, soluble in organic solvents, and suitable for coating of electrical wire and film forming, by reacting a specific aromatic tricarboxylic acid (derivative) with isophoronediamine.
CONSTITUTION: The objective polyamide-imide of formula (R is tri-falent organic group having aromatic group) is prepared by reacting (A) an aromatic tricarboxylic acid (derevative) [pref. trimellitic acid (anhydride)]with (B) isophorone in (C) an organic solvent (pref. cresol), in the presence of (D) an organic base (e.g. triethylamine, etc.) at 100W250°C.
