The present compositions and methods include the use of one or more reactive demolding agents. The reactive demolding agents react with components of a polymerization mixture to produce a polymerized silicone hydrogel device containing a reactant product of the demolding agent and the other components of the polymerization mixture. Polar resin molds used during the polymerization of the polymerization mixture are more easily separated than substantially identical molds used in the polymerization of a substantially identical material without a reactive demolding agent. The present compositions and methods may be used in the manufacture of silicone hydrogel lenses, such as contact lenses. The demolding aids may also be useful as delensing aids.Type: GrantFiled: March 15, 2007Date of Patent: September 21, 2010Assignee: CooperVision International Holding Company, LPInventor: Charles Francis

Patent number: 7786202Abstract: The invention relates to a process for preparing a layered double hydroxide comprising a charge-balancing anion, the process comprising the steps of: (a) preparing a precursor suspension or solution comprising a divalent metal ion source, a trivalent metal ion source, water, and a solvent which is miscible with water and in which at least 5 g/l of a charge-balancing anion precursor can be dissolved; (b) treating the precursor suspension or solution to obtain the layered double hydroxide, wherein the charge-balancing anion precursor is added to the suspension or solution before, during or after step (b), and wherein, if the charge-balancing anion is an organic anion, less than 50 wt % of the charge-balancing anion precursors, based on the total weight of charge-balancing anion precursors, is a salt, with the proviso that the charge-balancing anion is not carbonate. The invention further pertains to a layered double hydroxide obtainable by this process.Type: GrantFiled: December 4, 2006Date of Patent: August 31, 2010Assignee: Akzo Nobel N.V.Inventors: Elwin Schomaker, Robin Winters
