Abstract: A collagen-hydrogel for promoting epithelial cell growth and regeneration of the stroma is shown. Also shown is an optical lens for the eye, fabricated from the collagen-hydrogel, which, when affixed to Bowman's membrane, promotes and supports epithelial cell growth, enables corneal epithelium of the cornea of an eye, during the healing process, to attach to and cover the anterior surface of the lens implanting the same and to regenerate the stroma which grows over the edge of and attaches to the optical lens. Laid down in the layers of the regenerated stroma are new keratocytes and collagen fibial produced from keratocytes. The collagen-hydrogel is a hydrogel polymer formed by the free radical polymerization of a hydrophilic monomer solution gelled and crosslinked in the presence of an aqueous stock solution of collagen to form a three dimensional polymeric meshwork for anchoring collagen. The collagen-hydrogel material has a ratio by weight of collagen-to-hydrogel in the range of about 0.

Abstract: A method of making a collagen-hydrogel is shown. The method comprises the steps of forming a radical free polymer of a hydrophilic monomer; mixing the hydrophilic monomer with a stock solution of collagen in the presence of a weak solution of ammonium persulfate and sodium metabisuleate forming a clear viscous monomer solution; and heating said viscous monomer solution in the presence of a crosslinking agent to polymerize the same into a three dimensional polymeric meshwork having collagen from the stock solution of collagen interdispersed within the three dimensional polymeric meshwork.

Abstract: A novel inorganic filler-containing polyolefin resin composition exhibits high-level stiffness at a temperature in the vicinity of crystalline melting point of the matrix-forming polyolefin resin or even at a higher temperature. The composition comprises specified amounts of a matrix-forming polyolefin resin, a dispersion-phase-forming resin, and a fibrous or lamellate inorganic filler. In the composition, one end portion of an individual fiber or lamella of the fibrous of lamellate inorganic filler is embedded in the dispersion-phase-forming resin not uniformly miscible dispersed in the polyolefin resin and the other end portion of the individual fiber of lamella is also embedded in the dispersion-phase-forming resin located at a separate position, whereby the filler forms substantially a network structure via the dispersion-phase-forming resin.
