Silalkylene-siloxanes, fluorinated

This review concerns silalkylene siloxanes fluorinated or non fluorinated, aromatic or nonaromatic, but we have voluntarily excluded polysilanes, i.e. polymers that contain silicon but without any SiOSi bonds. 

In 1995-1996, several Japanese patents [53-56] were issued about new flu-orinated silalkylene-siloxanes which were shown to exhibit a high resistance to chain-scission by acid or alkali, but nothing was said about their thermal or mechanical properties. Only their surface properties, due to fluorinated side chains, were studied. 

So, finding a good combination of hybrid or silalkylene siloxanes, classical siloxanes, silarylene siloxanes, preferably fluorinated, remains a challenge to obtain the best elastomer.
