Abstract: The invention relates to compositions which are storage-stable at room temperature and which can be heat-cured to form molded parts having polyurethane, polyurea, and polyisocyanurate groups, said composition containing (a) one or more polyols having a molecular weight of from 400 to 10,000 and a functionality of from 2 to 8, (b) at least one polyfunctional compound having a molecular weight of 62 to 400 and being selected from the group consisting of aliphatic hydroxyl compound, cycloaliphatic hydroxyl compounds, aromatic amino compounds, or mixtures thereof, and (c) an organic polyisocyanate which is present in the form of discrete particles, which are deactivated on their surfaces and are dispersed in the liquid component, and depending on the product needs, (d) catalysts, (e) blowing agents, (f) reinforcing materials, and (g) auxiliaries and additives, The single-component systems are used for the preparation of cellular or noncellular, optionally reinforced polyurethane, polyurea, and/or polyisocyanurate group-containing molded parts.

Abstract: The invention relates to a process for the preparation of cellular, microcellular, and noncellular polyurethane polyurea molded parts with improved demolding characteristics through the reaction injection molding technique wherein unique internal mold release agents are used which are esters and/or amides prepared by reacting a mixture of montanic acid and a carboxylic acid having ten or more carbon atoms with a polyol, alkanolamine, or polyamine.

Abstract: In order to prepare thermoplastic polyurethane elastomers (a) organic diisocyanate, (b) polyhydroxyl compounds with molecular weights of 500 to 8,000, and (c) chain extenders with molecular weights of 60 to 400 in the presence of (d) catalysts, and optionally (e) auxiliaries, and/or (f) additives are reacted in two reaction stages at temperatures from 60 DEG C. to 250 DEG C. In the first reaction stage the components are continuously mixed, the reaction mixture is applied to a carrier, preferably a conveyor band of thermoplastic material, and is allowed to react at the reaction temperature until solidified. Subsequently, the solidified reaction mixture is melted in an extruder and the reaction is completed in the second reaction stage.

Abstract: The invention relates to a process for producing compact or cellular mouldings of polyurethane, polyurea or polyurethane-polyurea containing reinforcing agents by reacting a) organic polyisocyanates, b) compounds with molecular weights from 10,000 to 400 and at least two reactive hydrogen atoms and c) chain extenders and/or cross-linkers in the presence of d) fibre-containing reinforcing agents and, if appropriate, e) catalysts, f) blowing agents, g) auxiliaries and/or additives in closed moulds, the components (a) to (c) and, if appropriate (e) to (g) being processed as one-shot systems by the reaction injection moulding process and the fibre-containing reinforcing agents used comprising one or more polyurethane thermosets with a compressive strength (perpendicular to the plane of the mats) of 1.1 to 0.1 N/mm at 30 % compression, which contain, based on the total weight, 50 to 95 % by weight of a fibre-containing sheet-like structure.
