There is provided a trisiloxane having a 3-(meth)acryloxy-substituted (hydroxylcyclohexyl)ethyl group, useful in making water absorbing silicone-hydrogel films for biomedical devices, such as contact lens, and a process for producing these monomers. This invention also provides for copolymers made from the trisiloxane having a 3-(meth)acryloxy-substituted (hydroxylcyclohexyl)ethyl group described herein.

(Meth)acryloxy-containing trisiloxane, siloxane-containing polymers and biomedical devices therefrom

There is provided new mono-(meth)acrylate functionalized silicone monomers containing carbosiloxane linkage for improved hydrolysis resistance, useful in making water absorbing silicone-hydrogel films for contact lens applications. This invention also provides homo-polymers and copolymers made from the mono-(meth)acrylate functionalized hydrophilic silicone monomers described herein. Also provided is a process for producing the monomers and polymers described herein and contact lenses produced from the same.

Siloxane monomers containing hydrolysis resistance carbosiloxane linkage, process for their preparation and thin films containing the same for contact lens application

The invention relates to a method for separating emulsions of oil and water, the method comprising incorporating a demulsifying-effective amount of a polyorganosiloxane demulsifier into an emulsion comprising an oil phase and an aqueous phase. The invention also relates to compositions containing polyorganosiloxane demulsifier and the water and oil phases of an emulsion.
