    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.

    摘要: Curable coating agents, a process for the production of scratch-resistant coatings on plastics, and articles coated by this process.The coating agents are polycondensates ofa reaction product, containing two or more carbon-carbon double bonds and one or more hydroxyl or alkoxy groups per molecule, obtained from an olefinically unsaturated silane containing 2 or more hydroxyl or alkoxy groups, whose olefinically unsaturated organic radical is bonded via a C-Si bond, and a hydroxyl-containing .alpha., .beta.-olefinically unsaturated monomer,an olefinically unsaturated silane of the general formulaR.sup.1 --Si(OR.sup.2).sub.3 where R.sup.1 is a vinyl radical or an alkyl acrylate or alkyl methacrylate radical bonded to the Si atom via a C--Si bond and R.sup.2 is hydrogen or a saturated hydrocarbon radical, anda saturated silane of the general formula ##STR1## where R.sup.3 and R.sup.4 are saturated or aromatic hydrocarbon radicals,with or without an epoxide-containing silane which also contains hydroxyl or alkoxy groups; the polycondensate may additionally contain an olefinically unsaturated reaction product of acrylic or methacrylic acid and a polyalcohol or polyether-ol.The coating agent is used to produce scratch-resistant coatings on the surface of plastics.

    摘要: Binders for coating agents, which are polycondensation products from equimolar amounts of aromatic dicarboxylic acids and diols which contain from 5 to 50% molar of the total diol amount of a neopentylglycol ester of hydroxypivalic acid and which have a melting point range of from 60.degree. to 150.degree. and a K value of from 20 to 45. The products are particularly suitable for coating strip metal.
