    Abstract: The present invention is directed to new aromatic diamines containing sulfonic acid aryl esters corresponding to the formula ##STR1## wherein R.sub.1 represents hydrogen, an optionally branched C.sub.1 -C.sub.6 alkyl radical (preferably a methyl group), a C.sub.1 -C.sub.6 alkoxy radical or a halogen atom (preferably chlorine) andR.sub.2 and R.sub.3 which may be the same or different, represent hydrogen, an optionally branched C.sub.1 -C.sub.20 (preferably C.sub.1 -C.sub.6) alkyl radical, a C.sub.1 -C.sub.6 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.

    Abstract translation: 本发明涉及新的芳族二胺,其含有对应于式(Ⅰ)的磺酸芳基酯,其中R 1表示氢,任意支链的C 1 -C 6烷基(优选甲基),C 1 -C 6烷氧基或卤素 原子(优选氯)和可以相同或不同的R 2和R 3表示氢,任选支链的C 1 -C 20(优选C 1 -C 6)烷基,C 1 -C 6烷氧基或卤素原子(优选氯)。 本发明还涉及通过任选取代的磺基氯与任选取代的酚然后氢化反应生产上述含有磺酸酯的芳族二胺的方法。 最后,本发明涉及使用含有磺酸芳基酯的芳族二胺作为通过异氰酸酯加聚方法生产聚氨酯塑料的合成成分。
