Abstract:
The invention relates to a process for preparing hyperbranched polyhydroxybenzoic acid alkoxylates, comprising the steps of: (a) reacting at least one polyhydroxybenzoic ester with one or more alkylene oxides, optionally in the presence of a basic catalyst, (b) allowing the polyhydroxybenzoic ester alkoxylates formed in step (a) to react with transesterification to form hyperbranched polyhydroxybenzoic acid alkoxylates.
