Lens composition articles and method of manufacture

摘要: New copolymer composition, methods for processing the copolymers into optical devices and articles resulting therefrom, especially intraocular contact lenses having outstanding extended wear daily properties. The composition comprises, in weight percent: from 3% to 35% polyfluoroalkyl acrylate; 45% 65% acryloxyalkylpolysiloxane; 1% 15% acryloxyalkylsilanol; 2% 20% polyacryloxyalkylpolysiloxane; polyol polyacrylate polymerizable ethylenically unsaturated monomeric wetting agent such as acrylic acid. may also contain 0 acid ester of a monohydric alcohol no more than 20 carbon atoms 0.05% about 2.0% free radical initiator.
