    摘要: Stable melamine-polyoxyalkylene polyether polyol dispersions are prepared by the in situ reduction of melamine particles wherein 90 percent of the melamine particles have a particle size of less than 10 microns. Stabilizers for the melamine-polyol dispersion are selected from the group consisting of(a) silicic acids and silicates,(b) salts of perfluorinated alkyl carboxylic acids having 4 to 20 carbon atoms, salts of alkyl sulfonic acids and perfluorinated alkylsulfonic acids having 4 to 20 carbon atoms and polyperfluoroether polyols having molecular weights of 300 to 6000, and(c) salts of fatty alcohol sulfates having 6 to 30 carbon atoms.These dispersions are useful for the preparation of polyurethane foams.

    摘要: Cathodic electrocoating binders based on polycondensation products which contain amino groups and which are, at least partially, in the form of their ammonium salts or quaternary ammonium salts.The polycondensation products containing amino groups are obtained by adduct formation of p-hydroxyacetophenone with polymers containing epoxide groups, followed by reaction of these adducts with formaldehyde and a secondary amine.The electrocoating binders of the invention may be used for coating metallic substrates and give coatings which are particularly corrosion-resistant and adhere particularly firmly.

    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.
