PROCESS FOR THE PREPARATION OF AN ALIPHATIC, CYCLOALIPHATIC AND/OR ALIPHATIC-CYCLOALIPHATIC DI- AND/OR POLYURETHANE Abstract of the Disclosure A process for the preparation of an aliphatic, cycloaliphatic and/or aliphatic-cycloaliphatic di- and/or polyurethane comprising the steps of A. reacting a primary aliphatic, cycloaliphatic, and/or aliphatic cycloaliphatic di- and/or polyamine with urea and an alcohol at temperatures of 160°C to 300°C, and B. separating the ammonia and other by-products from the aliphatic, cycloaliphatic, and/or aliphatic-cyclo-aliphatic di- and/or polyurethane. One or more catalysts may be added to the reactants to increase the reaction rate. The aliphatic, cycloaliphatic, and/or aliphatic-cycloaliphatic di- and/or polyurethanes produced are valuable end and intermediate products. They can be transformed into the corresponding isocyanates which can then be used for the preparation of polyurethanes. |
