Polysilicic Acid Esters as Precursors to New Ceramic Materials
Two simple siloxane ester chains, (Si$\sb2$O) (OCH$\sb3$)$\sb6$ and (Si$\sb3$O$\sb2$) (OCH$\sb3$)$\sb8$, and a polysilicic acid ester based on the cubic (Si$\sb8$O$\sb $) core, (Si$\sb8$O$\sb $) (OCH$\sb3$)$\sb8$ were prepared. Synthesis of the di- and trisiloxane esters was achieved by reaction of …
