Abstract:
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.
