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 two-layer shoe sole comprising i) an outsole of high-density polyurethane-polyurea elastomers and ii) a throughsole or comfort sole of low density produced by the one-shot process with the aid of the high-pressure method (RIM) by reacting a) organic polyisocyanates, b) relatively high-molecular-weight polyols, c) chain extenders and/or crosslinking agents, in the presence of d) catalysts, e) blowing agents and optionally f) auxiliaries and/or additives, where the formative component (c) for the production of the outsole (i) comprises primary aromatic polyamines, preferably alkyl-substituted phenylenediamines, containing at least one bonded alkyl radical in the ortho-position to each amino group, at least one of the alkyl radicals comprising more than 3 carbon atoms.

Abstract: The invention relates to a process for the preparation of cellular or non-cellular polyurethane-polyurea molded articles. The new process involves the use of urethane and isocyanurate group modified 2,4- and/or 2,6-toluene diisocyanate mixtures as the polyisocyanate component to improve the flowability of the reaction mixture without adversely affecting the mechanical properties of the resulting molded articles.

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: Reinforced cellular or noncellular molded polyurethane parts are prepared by heating a mixture of reinforcing materials and a heat-curable composition of polyisocyanates and polyols in an open or closed mold, said composition being storage-stable at room temperature and containing, optionally, auxiliaries and additives. In said composition, the polyisocyanate is dispersed in the form of discreet particles having particle diameters from 0.1 to 150 mu m in the polyol and the polyisocyanate particles are deactivated on their surfaces such that from 0.01 to 20 equivalent percent of the total available isocyanate groups are deactivated and such that the ratio of free isocyanate groups to hydroxyl groups is from 0.7:1 to 2.5:1. The polyurethane molded parts are suitable for use as self-supporting trim parts, reinforcement parts, or molded parts for various applications.
