Abstract:
1. A process for preparing polyhydroxy-functional polysiloxanes comprising branched polyglycidol polyether radicals and having the general formula where Z=C RK=unbranched polyether radical composed of alkylene oxide units having 1-6 carbon atoms, and/or aliphatic and/or cycloaliphatic and/or aromatic polyester radical having a weight-average molecular weight of between 200 and 4000 g/mol, R=polyhydroxy-functional branched polyglycidol polyether radical, which consists of a branched polyglycidol group or contains a branched polyglycidol group, R R A=1-20, B=2-300, and C=0-20; and if C=0 then R
