HYDROPHILIC MACROMERS AND HYDROGELS COMPRISING THE SAME

摘要

A hydrophilic silicone macromer composition suitable for use in producing hydrogel polymer films from which biomedical devices such as contact lenses can be made. The hydrophilic silicone macromer comprises a polyether backbone comprising a silicone - containing pendant group. In one aspect, a hydrophilic silicone macromer is of the Formula 1 : Formula (1) The hydrophilic silicone macromer can be used to form a polymer and a hydrogel film suitable for forming contact lenses.
