ABSTRACT: The functional polyperoxides (FPPs) consist simultaneously of surface active fragments possessing a high affinity for polymer and mineral surfaces, and reactive fragments with peroxide groups. The FPP macromolecules can be deposited on a polymer or mineral substrate and further covalently attached to the substrate. Toward this end, unique changes of polymer surface properties can be achieved providing biocompatibility, antibacterial properties, etc.Synthesis of FPPs based on a new peroxide monomer, N-(tert-butylperoxymethyl)acrylamide, and acrylamide or octylmethacrylate for modification (activation) of planar or dispersed substrate surfaces is reported .Using two interconnected processes, the cross-linking of new FPP macromolecules and their grafting to polymer surface, the peroxidation of the polymer planar substrate was achieved. Polyolefin surfaces peroxidized with FPPs were used for further covalent grafting of macromolecules with polar functional groups � poly(acrylic acid), polyacrylamide, dextran etc.Radical polymerization of acrylamide on FPPs-modified silica particles (dispersed substrate), resulted in a formation of covalently grafted polyacrylamide (PAAm) macromolecules on silica. By further cross-linking, hydrogel networks containing dispersed particles were developed. Porous hydrogels with reinforced pore �walls� and improved physicochemical properties were formed after leaching out the porogen (silica particles).
