Abstract

Process for obtaining a solution of a polyurethane containing isocyanate-reactive groups, characterized in that it comprises reacting together, in a solvent inert with respect to the isocyanate groups, a mixture of (a) a molar proportion of a polyester, polyester esteramide or substantially linear polyether, (b) from 1.15 to 8.0 molar ratios of 3-isocyanatomethyl-3,5,5-trimethylcyclohexyl-isocyanate and (c) simultaneously or subsequently an amount of a chain extender, practically equivalent to the amount of diisocyanate in excess of that necessary for the reaction with the polyester, polyesteramide or polyether, until the solution has a viscosity of 1 to 1,500 poises at 25ºC; and then add an excess of isocyanate-reactive organic compound.
