<p>A polymer composition containing a cross-linkable polymer and at least one silanol condensation catalyst is characterised in that the silanol condensation catalyst is an acid anhydride, preferably a carboxylic acid anhydride, for example selected amongst aliphatic carboxylic acid anhydrides, aromatic carboxylic acid anhydrides and polymer carboxylic acid anhydrides. Stearic anhydride and benzoic anhydride are examples thereof. The acid anhydride catalyst may also be used in combination with conventional silanol condensation catalysts, such as dibutyl tin dilaurate.</p> |
