Abstract

Process for the production of polyamide-imides, characterized in that at least one diisocyanate corresponding to the general formula is reacted O = C = N - R - N = C - O wherein R represents a divalent radical containing at least two carbon atoms, and is an aliphatic radical, or an aromatic radical, or a cycloaliphatic radical, or a heterocyclic radical, substituted or unsubstituted, containing at least one of the N, O and S atoms, or several of these directly coupled radicals, or at least one of the following radicals: alkylene, dioxyalkylene, cycloalkylene arylane, (see formula), X being a divalent radical, alcohol, dioxyalkylene, cycloalkylene, or arylene; Y and Y ', alcoholic radicals, aryls or cyclanyls, with at least one carbonylated compound capable of providing, at the same time, an amide and an internal imide, and containing, on the one hand, a carboxyl group and, on the other, a pair of carbonyl groups attached, each, on the one hand, to a different carbon atom of the same trivalent radical, and on the other, to an oxygen atom, and the two carbonyls being separated by at most three carbon atoms and the carboxyl group being separated from each of the carbonyl groups, by at least two carbon atoms, by putting the compounds in reaction in a solvent, in the molar ratio 1: 1.
