Abstract

PURPOSE: To prepare the titled composition with excellent heat resistance and craze resistance, by making a specified polyamide-imide resin acid water-soluble by the conversion of at least part of the carboxyl group thereof to its ammoninum salt.
CONSTITUTION: A (cyclo)alkanetricarboxylic acid (e.g., 1,2,4-butanetricarboxylic acid) having a 3W6C alkane group is reacted with an aliphatic, alicyclic or aromatic diamine in a water-soluble solvent boiling at 60W300°C (e.g., diethylene glycol), at a temp. from 60°C up to its b.p., to an extent of 30W3% residual acid value, to obtain a polyamide-imide resin acid. Then the polyamide-imide resin acid is made water-soluble by the conversion of at least part of the carboxyl group thereof into its ammonium salt by neutralization with ammonia.
EFFECT: It is possible to obtain a water-soluble resin composition with excellent flexibility, heat resistance, electrical insulation properties, etc., useful as an electrical insulating paint, an adhesive, etc.
