Organopolysiloxanes with Bunte salt groups, their synthesis and use for the surface treatment of inorganic or organic materials

摘要: Organopolysiloxanes with Bunte salt groups having the formula ##EQU1## being linked to a silicon atom by way of carbon and in which R1 is methyl proviso that up 10% may be alkyl 18 atoms or vinyl phenyl, hydrogen hydroxyl, R2 ##STR1## group ##STR2## group, one R3, R4 represents an OH other --S2 O3 Me (Me=alkali optionally substituted ammonium group), whereby R3 radicals can hydroxyl together oxygen oxirane ring amount 50% has any value from 1 2.33 b 0.02 1. The compounds synthesized corresponding organopolysiloxanes epoxy reaction alkali thiosulfate used for surface treatment inorganic organic materials, example, textiles, paper rock wool.
