Patent

CA 2171791

Polyurethanes and/or polyurethane ureas which are optionally cellular are produced by the process of the present invention. This process consists of reacting at least one polyisocyanate with a specific reaction mixture. This reaction mixture contains A) non-basic compounds having a molecular weight of 62 to 10,000 and containing at least two hydroxyl groups; and B) at least one component selected from: B)1 ) basic polyhydroxyl compounds and B)2) acids or the salts thereof; and C) at least one component selected from: C)1 ) fatty acids and C)2) the salts of the fatty acids. The reaction occurs at temperatures of from 0 to 150°C, and component A) is used as an at least 50 wt.% aqueous solution.
