Abstract

Described is a method for synthesizing polymer compounds (P), preferably polysiloxanes, comprising at least one carboxylic ester group, in particular (meth)acrylate-containing polysiloxanes, said method being carried out in the presence of conversion products (U) of metal salts, in particular chromium(III) salts, and conversion products of aldehydes and primary amines.
