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.

Curable polymers

The invention relates to the use of polyethers containing urethane or urea groups as foam stabilizers, obtained by reacting at least one isocyanate with (a) at least one hydrophilic polyether which statistically carries at least one OH and/or NHand/or NH function and (b) at least one hydrophobic polyether which statistically carries at least one OH and/or NHand/or NH function and optionally (c) further compounds which carry at least one OH and/or NHand/or NH function and/or other isocyanate-reactive groups, such as carboxyl or epoxide functions, with the proviso that at least one isocyanate is &#x2267;difunctional.
