<p>Hydrogels are prepared by subjecting to polymerization conditionsan aqueous mixture comprising a major amount of an organic compound which is characterized by a polymerizable ethylenic group (>C=C<) 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 permeabilty and good mechanical strength characteristics.</p> |
