A process of producing polyurethanes which are optionally cellular, by reacting a) polyisocyanates with b) mixtures comprising i) salts of fatty acids with basic polyols and ii) non-functional fatty acid esters and/or hydrocarbons, and, optionally, c) compounds of molecular weight 62 to 399 having at least two hydrogen atoms which are active in relation to isocyanates, and, optionally, d) compounds of molecular weight 400 to 10,000 having at least two hydrogen atoms which are active in relation to isocyanates, optionally, in the presence of e) foaming agents, catalysts and other process materials and additives known in the art. This invention also relates to the polyurethanes produced by this process. |
