57 Aminobenzol-alkylsulfone bzw. Aminobenzol-alkylsulfoxide der Formel
mit den in der Beschreibung genannten Substituentenbedeutungen erhält man in guten Ausbeuten durch Oxidation der entsprechenden Thioether in wäßrigem Medium bei pH-Werten von etwa 3 bis 14.
An object of the present invention is to provide a curable composition made mainly of an organic polymer having a reactive silicon group, exhibits a good curability without using any organic tin compound substantially, and gives a cured product having a sufficient strength; and to provide a catalyst composition. The object is solved by a curable composition, comprising a polymer (A) having a silicon-containing group which can be crosslinked by forming a siloxane bond, and a fluoride salt compound (B).
