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. © 1998 John Wiley & Sons, Inc.
