  • Biologically stabilized compositions comprising collagen as the minor component with ethylenically unsaturated compounds used as contact lenses
    Patent number: 4452925
    Abstract: Hydrogels are prepared by subjecting to poymerization conditions an aqueous admixture comprising a major amount of an organic monomer which is characterized by a polymerizable ethylenic group ##STR1## as illustrated by N,N-dimethylacrylamide, 2-hydroxyethyl methacrylate, dimethylaminoethyl methacrylate or methoxytriethylene glycol methacrylate, and a minor amount of solubilized collagen. The reactants employed are at least partially soluble in the aqueous reaction medium. The hydrogels thus prepared are novel shaped articles having utility in the medical and cosmetic fields. Contact lenses of such hydrogels exhibit high water content, high oxygen permeability and good mechanical strength characteristics.
    Type: Grant
    Filed: February 9, 1981
    Date of Patent: June 5, 1984
    Assignee: National Patent Development Corporation

  • Biologically stabilized compositions comprising collagen as the major component with ethylenically unsaturated compounds used as contact lenses
    Patent number: 4388428
    Abstract: Biologically stabilized compositions are prepared by subjecting to polymerization conditions an aqueous admixture comprising from 50 to about 70 weight percent solubilized collagen and from about 30 to less than 50 weight percent of an organic compound which is characterized by a polymerizable ethylenic group (>C.dbd.C<) as illustrated by N,N-dimethylacrylamide, 2-hydroxyethyl methacrylate, dimethylaminoethyl methacrylate or methoxytriethylene glycol methacrylate. The reactants employed are at least partially soluble in the aqueous reaction medium. The hydrogels thus prepared can be in the form of novel shaped articles having utility in the medical and cosmetic fields. Such hydrogels exhibit good biological stability, high water content, high oxygen permeability and sufficient mechanical strength characteristics to be useful as contact lenses.
