  • Polymeric compositions useful in oxygen permeable contact lenses
    Patent number: 5346978
    Abstract: Carboxylic acid esters devoid of beta hydrogens are homopolymerized or copolymerized with contact lens organic materials to form desirable contact lens materials and contact lenses. These materials have good contact lens properties, including desirable DK values, hardness, machineability and a desirable refractive index of at least 1.
    Type: Grant
    Filed: June 29, 1993
    Date of Patent: September 13, 1994
    Assignee: Polymer Technology Corporation
    Inventors: Richard C. Baron, Scott D. Rothenberger
  • Aqueous coating compositions
    Patent number: 5283299
    Abstract: Aqueous-based crosslinkable coating composition comprising an aqueous dispersion of at least one polymer having epoxy-reactive functional groups, at least one polyepoxide compound, and at least one metal chelate complex epoxy-cure catalyst.
    Type: Grant
    Filed: May 7, 1992
