Abstract:
The invention relates to a method for production of polyhydroxyfunctional polysiloxanes with branched polyglycidol polyether groups, in which firstly at least one allylic or methallylic starting material is reacted with at least one glycidol, such that an allyl polyether or methallyl polyether is formed, and then the allyl polyether or methallyl polyether thus produced is added to a Si—H functional alkyl polysiloxane in the presence of an acid buffering agent. The invention further relates to polysiloxanes, which may be obtained by said method and the use of the polysiloxanes in coating agents, polymeric coating masses and thermoplastics.
