The crude fibrin which is hitherto discarded as waste in slaughterhouses was recovered and purified. Using this fibrin, fibrin-gelatin composites were prepared and crosslinked with either basic chromium sulfate or glutaraldehyde. These composites were also graft-copolymerized with polyhydroxyethyl methacrylate using hydrogen peroxide-ferrous ammonium sulfate initiation technique. The graft copolymers were characterized for their moisture content, water absorption capacity, tensile strength, infrared spectroscopy, scanning electron microscopy, and thermogravimetric profile.
