摘要:
The present invention provides a silicone hydrogel comprising a reaction product of a monomer mixture for forming the silicone hydrogel and water, wherein the water is present in an amount not less than 50 wt % based on the total weight of the silicone hydrogel. The monomer mixture comprises at least one silicon-containing monomer and at least one ionic monomer, wherein the ionic monomer is present in an amount not less than 0.7 wt % based on the total dry weight of the silicone hydrogel. The present invention also provides ocular articles made from the silicone hydrogel.
摘要:
The present invention provides a reactive hydrophilic polymer comprising units of Formulae (I) and (II): wherein the ratio of the mole number of the unit of Formula (I) to the total mole number of the units of Formulae (I) and (II) is from 0.002 to 0.04, and the reactive hydrophilic polymer has a molecular weight from 10,000 to 2,000,000. The present invention also provides a silicone hydrogel comprising the reactive hydrophilic polymer and ocular articles made therefrom.
