摘要:
Organopolysiloxanes with Bunte salt groups linked over carbon atoms are disclosed, as well as methods for the synthesis of these compounds by the reaction of organopolysiloxanes having epoxy groups with, in relation to the epoxy groups, equimolar amounts of Me.sub.2 S.sub.2 O.sub.3, in which Me is an alkali metal or an optionally substituted ammonium group. The compounds may be used for the permanent finishing of fibers or fiber products or for the treatment of hair.

摘要:
Organopolysiloxanes with Bunte salt groups having the formula ##EQU1## the Bunte salt groups being linked to a silicon atom by way of a carbon atom and in whichR.sup.1 is methyl with the proviso that up to 10% of the R.sup.1 groups may be alkyl with up to 18 carbon atoms or vinyl phenyl, hydrogen or hydroxyl,R.sup.2 is the ##STR1## group or the ##STR2## group, in which one of the R.sup.3, R.sup.4 groups represents an OH group and the other an --S.sub.2 O.sub.3 Me group (Me=alkali or the optionally substituted ammonium group), whereby the R.sup.3 and R.sup.4 radicals can be hydroxyl or together the oxygen of an oxirane ring in an amount up to 50% of the R.sup.2 group,a has any value from 1 to 2.33 andb has any value from 0.02 to 1.The compounds can be synthesized from the corresponding organopolysiloxanes having epoxy groups by reaction with alkali or ammonium thiosulfate and used for the surface treatment of inorganic or organic materials, for example, textiles, paper or rock wool.
