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.
