Abstract
PURPOSE: To obtain titled resin having excellent heat resistance and mechanical properties, by reacting a compound having a cyclic acid anhydride structure with a high-molecular reaction product obtained by reacting an acid anhydride with a diisocyanate compound.
CONSTITUTION: 1mol of (a) an acid anhydride compound selected from the group consisting of aromatic tricarboxylic acid anhydride and aromatic tetracarboxylic acid anhydride, such as trimellitic anhydride is reacted with at least 1mol of (b) a diisocyanate compound such as toluylene diisocyanate to produce a high-molecular reaction product (A). Then, the reaction product (A) is reacted with (B) a compound having a cyclic acid anhydride structure, such as pyromellitic anhydride or phthalic anhydride to produce the polyamideimide of the purpose, said compound (B) being used in a molar amount equal to or less than the excess mols of compound (b) used.
