Abstract: Low-shrinkage nylon moldings are produced by activated alkaline lactam polymerization, preferably using the reactive injection molding technique, by a process wherein the polymerization is carried out in the presence of from 5 to 80% by weight of a polymer P which 1. is completely soluble in the lactam, 2. separates out in the course of polymerization at a conversion of from 1 to 50%, 3. is composed of one or more blocks which are compatible with polylactam and one or more blocks which are incompatible therewith, and preferably 4. possesses functional groups which are incorporated into the growing polylactam chain.

Abstract: Discolouration and other effects which interfere with polymerization in the preparation of fibre-reinforced polyamide (nylon) by alkaline polymerization of lactams in the presence of fibre materials do not occur if the fibre materials are pretreated with an organic polyfunctional isocyanate.

Abstract: The invention relates to a one-shot process for the preparation of cellular or noncellular polyurethane polyurea parts having a modulus of flexural elasticity greater than 600 N/mm2 and densities of from 0.8 to 1.2 g/cm3 using the reaction injection molding technique, by reacting organic polyisocyanates, a polyol component, aromatic diamines, additional chain extenders and/or cross-linking agents in the presence of catalysts and optionally blowing agents, auxiliaries and/or additives, wherein the polyol component is a mixture containing (i) from 95 to 60 percent by weight of at least one compound selected from the group consisting of polyols, polyether polyamines, polyesteramides, and their mixtures having functionalities of from 2 to 6 and a molecular weight of from 1000 to 8000 and (ii) from 5 to 40 percent by weight of a least one aromatic and/or aromatic-aliphatic polyester polyol having a functionality of from 2 to 3 and a molecular weight of from 254 to 700, wherein the percents by weight are based on the total weight of the polyol component.

Abstract: The invention relates to storage-stable tris(hydroxyalkyl)isocyanurate polyol dispersions containing (a) from 2 to 70 parts by weight tris(hydroxyalkyl)isocyanurate, (b) from 98 to 30 parts by weight of at least one polyol having a functionality of from 2 to 8 and a hydroxyl number from 20 to 1800, and (c) from 0 to 20 parts by weight of one or more dispersion stabilizers. The dispersions are prepared by dissolving starting components A and B at temperatures in excess of 100 DEG C., in some cases adding a dispersion stabilizer and/or crystallization accelerator, with continuous and step-wise cooling of the mixture while stirring. The products are utilized for the preparation of polyurethane plastics, in particular polyisocyanurate foams containing polyurethane or polyurethane groups.

Abstract: 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.

Abstract: Process for the manufacture of polyester imides. Melamine, an at least tribasic carboxylic acid, a polyhydric alcohol and, optionally, an aromatic dicarboxylic acid are condensed at elevated temperature. The polyester imides are suitable, in the form of solutions, aqueous dispersions or melts, for use as baking enamels for metallic conductors.

Abstract: 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.
