Acrylic monomers were graft copolymerized onto gelatin chains using potassium persulfate in aqueous medium. The graft copolymers were then treated with glutaraldehyde to establish crosslinks between gelatin macromolecules. This yielded a rigid water insoluble protein network sporting grafted chains at random. The chemistry of the acrylic monomer decided the hydrophilic/hydrophobic properties of the ultimate product. This paper describes the preparation and properties of such grafted, crosslinked gelatins.
