Abstract
A hydrophilic silicone polymer composition suitable for use in producing hydrogel polymer films disclosed. In one aspect, a hydrophilic silicone monomer is of the Formula 1:wAmBnw (1)where A is a divalent block comprising a silicone-containing pendant group. In one embodiment, the silicone-containing pendant group comprises polyalkylene oxide groups. The structure of the polymer can be controlled and tuned to provide a material with excellent wettability and oxygen permeability. The polymers are suitable for use in a variety of applications including in providing a film for forming contact lenses.
