    摘要： The manufacture of paper-like and textile-like sheet materials by the use of fibrids which have been obtained by dissolving poly(amide-imide) resins in an organic solvent, mixing the resulting solution with a liquid which is a non-solvent for the polymer and introducing the resulting solution into a liquid precipitation medium while exposing it to shearing forces.The present invention relates to the use, for the manufacture of paper-like and textile-like sheet materials, of novel fibrids, which have been obtained by dissolving poly(amide-imide) resins in an organic solvent, mixing the resulting solution with a liquid which is a non-solvent for the polymer and introducing the resulting solution into a liquid precipitation medium while exposing it to shearing forces.

    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.
