Organopolysiloxanes comprising polyhydroxyorganyl radicals and polyoxyalkylene radicals

An organopolysiloxane copolymer comprising on average at least one polyhydroxyorganyl group and/or sugar group or sugar-derivative group, attached to the siloxane via a spacer, and on average at least one polyoxyalkylene group, of the general average formula ##STR8## where R.sub.1 =alkyl radical of 1 to 4 carbon,

• R.sub.2 =R.sub.1, R.sub.3 and/or R.sub.4,
• and where the indices a, b, and c are integers within the stated ranges
• a=0 to 200,
• b=0 to 50,
• c=0 to 50,
• with the proviso that at least one radical R.sub.3 and R.sub.4 is present in each case,
• R.sub.3 =polyoxyalkylene of the general average formula
• --R.sub.5 --(C.sub.2 H.sub.4 O).sub.d --(C.sub.3 H.sub.6 O).sub.e --(C.sub.4 H.sub.8 O).sub.f --R.sub.6 where
• d=0 to 100,
• e=0 to 100,
• f=0 to 100,
• with the proviso that at least one of the indices d, e or f is.gtoreq.1,
• R.sub.5 =alkyleneoxy radical having 1 to 20 carbon atoms which is optionally branched and/or can contain double bonds,
• R.sub.6 =hydroxyl, alkoxy or acyloxy radical having 1 to 20 carbon atoms,
• R.sub.4 =radical of the general formula --R.sub.7 --PH, the radical R.sub.7 functions as a spacer between siloxane skeleton and polyhydroxy-organyl radical and/or sugar radical, with the exception of a polyether radical,
• PH is a polyhydroxyorganyl radical containing a defined number n of (C--OH) groups, where n is.gtoreq.2.
