    Abstract: A method of hardening gelatin is described which uses (1) a polymer containing at least 0.01 mol % of a repeating unit represented by formula (I) ##STR1## wherein R represents a hydrogen atom, an alkyl group having from 1 to 6 carbon atoms, or a halogen atom, M represents a hydrogen atom, an alkali metal atom, an alkaline earth metal atom, or an organic base, X represents an alkyl group having from 1 to 6 carbon atoms, an alkoxy group having from 1 to 6 carbon atoms, an alkylamino group having from 1 to 6 carbon atoms, or a halogen atom, m represents 0, 1 or 2, and n represents 1 or 2, (2) a polyvalent alcohol having at least two hydroxy groups, and (3) a hardener having an active vinyl group.The method has advantages in that the rate of hardening the gelatin is fast, the so-called post hardening property is small, and the gelatin composition is hardely influenced by the conditions of temperature and humidity during storage.

  • 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.
