Abstract
Novel polyamide-imide resin compositions, useful for electrically insulating conductors, are prepared by polycondensing a tribasic acid anhydride compound and a diisocyanate in an inert organic solvent in the presence of a catalytic amount of an oxyanion or amine compound at a high solids content, and controlling the reaction to prevent a great increase in viscosity.
