摘要: A polyamide-imide precondensate which is solid at room temperature, but is fusible and soluble in polar solvents. It is manufactured by first condensing 1 mole of diamine with 2 moles of tricarboxylic acid anhydride in a diol as the solvent, to give a diimide-dicarboxylic acid, then esterifying the diimide-dicarboxylic acid with the diol and finally effecting the polycondensation by adding 1 mole of diamine per mole of diester. The precondensate may be used, as a melt, as a solution in organic solvents or as an aqueous dispersion, for coating electrical conductors.
