METHOD FOR THE PRODUCTION OF POLYMERIZABLE SILICONES

Polymerizable siloxy-substituted silanes are obtained in high yield and purity by adding a substituted alkoxysilane to a mixture of disiloxane, acetic acid, sulfuric acid, and optionally an acidic catalyst, separating a product phase from an acidic phase, adding hexamethyldisilazane to the product p...

Zusammenfassung:Polymerizable siloxy-substituted silanes are obtained in high yield and purity by adding a substituted alkoxysilane to a mixture of disiloxane, acetic acid, sulfuric acid, and optionally an acidic catalyst, separating a product phase from an acidic phase, adding hexamethyldisilazane to the product phase and filtering off a resulting salt, followed by distillation.
