    摘要: A polysiloxane comprises diaryl, dialkyl, and arylalkyl siloxane units, and further has at least a functional group. Such polysiloxane can be further copolymerized with an additional monomer to produce polymeric compositions suitable for making ophthalmic devices. The additional monomer can be selected to produce desirable properties for ophthalmic applications, such as high refractive index and/or high elongation.
