摘要： This application relates to textile sheets which have been coated with polyurethanes and to a process for coating said textile sheets wherein a solution of polyurethane is applied as a top coat to a release substrate and then a bonding coat is applied before application of the textile material. The polyurethane which is used as a top coat is prepared by reacting a dihydroxyl compound with a molecular weight between about 600 and 4000 and a mixture of at least 2 diols with a molecular weight between 62 and 450 with at least one organic diisocyanate. The invention overcomes the difficulty of the top coat being lifted from the release substrate in numerous areas while other areas remain firmly attached giving the so-called "hoar-frost" effect.

摘要： This invention relates to an improved process for the production of high molecular weight polyurethanes which are free from isocyanate groups and are soluble in organic solvent in reduced reaction times. The reactants, polyol and isocyanate, for example, are mixed together with solvent and the temperature is permitted to rise under the effect of the heat of reaction. The reaction mixture is then cooled with solvent addition in such a way that the viscosity of the reaction mixture remains constant until the optimum temperature for the polyurethane formation reaction ("specific reaction temperature") is reached. The mixture is then gradually cooled until there is no residual isocyanate present and the polymer is recovered from the reaction mixture.
