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.
Polyoxaethylene polypodands - powerful reduction catalysts in solid-liquid and liquid-liquid phase transfer systems
properties of polypodands, esters of inorganic acids, as phase‐transfer catalysts have been reported previously. Unfortunately, these compounds are unstable under hydrolytic conditions. A group of new, hydrolytically stable podands has been synthesized. Their complex forming abilities towards alkali metal ions have been studied. The podands studied have been used as catalysts in phase transfer catalysis
