  Dissolved or dispersed thermoset resins compositions comprising at least 10% by weight of a polymerizable material and up to 90% by weight of a solvent or a dispersion medium, the molecularweightofthe resins being by preference at least 500, may be thickened by the addition of a polyfunctional isocyanate and a trimerisation catalyst. The thickened compositions can be cured by a free radical catalyst and the application of heat and/or pressure. A variety of reinforced articles can be produced from the thickened compositions.

  Aqueous dispersions of polyurethane polymers in ammonium salt form are prepared by reacting diisocyanates with a polyhydroxy, carboxylic acid to form an isocyanate- terminate prepolymer that is united with an unsaturated fatty acid ester polyol to provide carboxylic-containing, water-dispersible polyurethanes having properties exhibited by organic solvent-based, oil-modified polyurethanes. The aqueous dispersions can be formed by neutralization of "oil-modified," carboxylic group-containing, water-dispersible polyurethanes with ammonium salt-forming materials such as ammonia and amines. The aqueous dispersions are especially desirable coating compositions. An organic phosphite may be incorporated in the compositions to control the development of hardness in films made from the aqueous dispersions and thereby avoid the formation of wrinkles in films that are made from the compositions.

  通过将二异氰酸酯与多羟基羧酸反应，形成异氰酸酯终止的预聚物，该预聚物与不饱和脂肪酸酯多元醇结合，提供含羧基的水分散性聚氨酯，该聚氨酯具有有机溶剂基油改性聚氨酯所显示的特性。水性分散体可通过 "油改性"、含羧基、水分散性聚氨酯与形成铵盐的材料（如氨和胺）进行中和而形成。水性分散体是特别理想的涂料组合物。组合物中可加入有机亚磷酸酯，以控制水性分散体制成的薄膜的硬度，从而避免组合物制成的薄膜起皱。
