Abstract: The invention describes a process for harmonizing the reaction rates for the formation of urethane and isocyanurate groups during the preparation of polyurethane-polyisocyanurate foams by reacting organic polyisocyanates with polyols in the presence of blowing agents and salts of amines having the formula as catalysts, wherein R stands for an hydrogen atom or a straight chained or branched alkyl radical with 1 to 19 carbon atoms, and n and m are equal or different whole numbers from 2 to 10.

Abstract: The subject of this invention is a process for the preparation of lightweight, planar molded articles, e.g. those having a thickness from 0.1 to 40 mm and having a density of 0.015 to 0.25 g/cm3, by treating porous materials, preferably open celled or flexible or semi-rigid polyurethane foams, with an effective amount of an aqueous dispersion or emulsion of organic compounds containing NCO groups and allowing the isocyanate compound to cure, optionally while molding, at a temperature from 25 DEG C. to 180 DEG C. and optionally at a pressure of 1 to 50 bar. The invention also relates to molded articles prepared according to this process which have special mechanical properties.

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: Light flat moulded parts (I) are mfd. by treating porous materials (II) with an organic cpd. (III) contg. an effective amt. of NCO gps. and hardening, with shaping as required; the novelty is that (III) is used in aq. dispersion or emulsion, which is used to impregnate open-cell foam materials (IV) and then crosslinked. PU parts (I) have thickness, 0.1-40 mm; density, 0.015-0.25 g/cm3; tensile strength 100-500 kPa; elingation at break 10-70%; compression hardness, 10-100 kPa at 40% deformation; thermal flexural strength (DIN 53424), 100-160 deg.C.

Abstract: Storage-stable crystallite suspensions which contain a) from 5 to 35% by weight of a polyester prepared from isophthalic acid, terephthalic acid or mixtures of terephthalic acid and aromatic and/or aliphatic dicarboxylic acids, and alcohols having 1 to 6 carbon atoms, having a melt viscosity at 150 DEG C of from 15 to 3000 mPas, as the disperse phase, b) from 65 to 95% by weight of a polyhydroxyl compound having a melting point of below 30 DEG C as the coherent phase, the % by weight data being based on the total weight of components (a) and (b) and c) from 0.2 to 7 parts by weight per 100 parts by weight of the crystallite suspension comprising components (a) and (b), of at least one aliphatic and/or cycloaliphatic amine, alkanolamine and/or product of the reaction of said amines and/or alkanolamines with components (a) and/or (b). The crystallite suspensions are suitable for the preparation of compact or cellular polyurethane plastics or polyisocyanurate plastics containing polyurethane groups, where the polyester (a) of the disperse phase is fully incorporated into the polyurethane skeleton.
