Resumen:

Radiation processing has many advantages over other conventional methods. When using gamma radiation for material processing, no catalysts or additives are needed to initiate the reaction. Grafting techniques normally include the pre-irradiation, as well as the mutual or the simultaneous method. The main advantage of this radiation-assisted method is relatively simple; surface grafting of polymers has attracted great interest in the past few decades, as it allows the tailoring of surface properties of various polymer materials, and thus specific functionalities useful for many applications can be effectively produced. When polymers are exposed to ionizing irradiation, trapped radicals and peroxides or hydroperoxides are formed, and they are capable of initialing grafting copolymerization reactions. Various graft-polymerization approaches have been developed, including direct graft polymerization of vinyl monomers already containing desirable functional groups, graft copolymerization of two (or more) different types of monomers onto a polymer backbone, and graft polymerization of a precursor monomer that can be subsequently modified. This chapter revises and focuses the recent advances in the synthesis and characterization of graft copolymers with new architecture prepared by means of gamma radiation. Also, it describes the potential use of these copolymers in the biomedical area.
