权利人:BAYER AG
摘要:The present invention is directed to new aromatic diamines containing sulfonic acid aryl esters corresponding to the formula 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.

权利人:BAYER AG
摘要:The present invention is directed to the preparation of optionally pigmented spreading paste based on multiphase mixtures of ionically-modified polyurethanes and/or polyurethane ureas which are prepared from special synthesis components based on silicone resins, aromatic hydroxypolyethers, aromatichydroxy polyesters, and perfluorocarbon resins, the multiphase mixtures additionally containing water and organic solvents for the polyurethanes and/or polyurethane ureas. The present invention is also directed to the preparation of these optionally pigmented spreading pastes and to their use for the production of coatings permeable to water vapor on fabric or leather substrates by the direct or transfer method using the technique of evaporation.
