Abstract
Disclosed herein are solid polysiloxane polymers having multiple oligooxyethylene side chains per silicon. The multiple oligooxyethylene side chains are each directly connected to the silicons, or they can be linked by a branching structure and then jointly linked to the silicons. Methods for producing these compounds, and intermediates which are disubstituted silicon compounds, are also disclosed. These materials are highly conductive, and thus appear particularly useful in lithium automotive batteries.
