Abstract
A process for stabilizing organopolysiloxanes containing alkaline compounds such as alkali metal hydroxides, alkali metal silanolates, alkali metal siloxanolates, or a mixture of at least two such compounds, which comprises neutralizing the alkaline compound present in the organopolysiloxanes with a neutralizing agent selected from a compound containing carbon, hydrogen, and oxygen atoms, and optionally at least one halogen atom, in which the compound has 2, 3 or 4 hydrocarbon groups bonded to the same carbon atom via oxygen, or an acylacetic acid ester. The resultant organopolysiloxanes are stabilized against viscosity changes caused by the alkaline compounds.
