Neutralization of alkali metal catalysts in organopolysiloxanes |
| abstract |
A process for the neutralization of the alkali metal catalyst in a polymerized organopolysiloxane, where the alkali metal content of the resulting organopolysiloxane is significantly reduced, is described. The process consists of neutralizing the alkali metal salt with a straight-chain carboxylic acid of general formula ZCOOH, where Z is a hydrocarbon group containing at least two carbon atoms, and thereafter filtering the organopolysiloxane. The same ZCOOH carboxylic acids may be added to organopolysiloxanes which have previously been neutralized with eithercarbon dioxide or acetic acid in orderto significantly reduce the alkali metal content of the organopolysiloxane after filtration. Organopolysiloxanes containing less than 0.5 ppm K + can be easily obtained. |
