Abstract

An attempt has been made in the paper to impart flame retar dancy to polymers with grafting induced by the electron-beam (EB) pre- irradiation technique. Based on EVA copolymers with different VA contents (%), the authors have tried to use EB pre-irradiation under atmosphere fol lowed by grafting with/without subsequent saponification expediting the char ring of polymers upon heating. Characterization of the flammability of the irra diated EVA copolymers grafted with acrylic monomers (MAA, AA, and AAm) indicates that this approach turns out to be promising and worth pursuing in research and/or in applications.
