Mo-3031 AROMATIC DIAMINES CONTAINING SULFONIC ACID ARYL ESTERS, A PROCESS FOR THEIR PRODUCTION AND THEIR USE IN THE PRODUCTION OF POLYURETHANE PLASTICS ABSTRACT OF THE DISCLOSURE The present invention is directed to new aromatic diamines containing sulfonic acid aryl esters corresponding to the formula Image wherein R1 represents hydrogen, an optionally branched C1-C6 alkyl radical (preferably a methyl group), a C1-C6 alkoxy radical or a halogen atom (preferably chlorine) and R2 and R3 which may be the same or different, represent hydrogen, an optionally branched C1-C20 (preferably C1-C6) alkyl radical, a C1-C6 alkoxy radical or a halogen atom (preferably chlorine). The present invention is also directed to a process for the production of the above aromatic diamines containing sulfonic acid esters by the reaction of optionally substituted sulfochlorides with optionally substituted phenols followed by hydrogenation. Finally, the present invention is directed to the use of aromatic diamines containing sulfonic acid aryl esters as a synthesis component for the production of polyurethane plastics by the isocyanate polyaddition process.
