摘要： Cross-linked polyurethanes such as solid elastomeric polyurethanes or microcellular polyurethanes are prepared by reacting a polyisocyanate, one or more polyols and at least one trihydroxy compound in the presence of a catalyst using, as the hydroxyl compounds a low molecular weight diol, optionally a polymeric polyol and tris-(.beta.-hydroxypropyl)-isocyanaurate or ethoxylated tris-(.beta.-hydroxypropyl)-isocyanurate all present in specific ranges of proportions. Use of the specific isocyanurates provides for better utilization and smaller quantities of the blowing agent used to make microcellular polyurethane foams.

摘要： Single-component or two part polyurethane-based lacquers are prepared on the basis of a polymeric polyhydroxy compound having a high molecular weight in the range of 300 to 5000, such as poly(oxytetramethylene)glycol, a low molecular weight diol such as ethylene glycol, at least one isocyanate such as toluene diisocyanate and tris-(.beta.-hydroxypropyl)-isocyanurate or its ethoxylated derivative together with the customary accelerators, additives, solvents and the like used in lacquer manufacture. These lacquers exhibit exceptional hardness, high impact resistance, good adhesion to the substrate to which they are applied as well as corrosion resistance.

摘要： An improved process for the preparation of tris-(.beta.-hydroxypropyl) isocyanurate by the reaction of propylene oxide with cyanuric acid. Propylene oxide and cyanuric acid are reacted at a temperature of between about 100.degree. and 150.degree. C. at an elevated pressure, and in the absence of a catalyst, in a reaction medium of a polyhydroxy compound which is a liquid at the reaction temperature and in which the tris-(.beta.-hydroxypropyl) isocyanurate is soluble or with which it is miscible.
