Title:
ALKOXY POLYSILOXANES AND METHODS OF MAKING ALKOXY SILANES AND SILOXANES
Document Type and Number:
WIPO Patent Application WO/2014/099497
Kind Code:
A3
Abstract:
Methods of making alkoxy polysiloxanes, as well as alkoxy-substituted silanes are described. Generally, the methods involve the reaction of an alcohol with a hydrosilane or a hydrosiloxane in the presence of a palladium or platinum catalyst. Alkoxy polysiloxanes, including linear and branched alkoxy polysiloxanes are also described.
