APPROACHES TO THE FLAME RETARDANCY OF POLYMERS .1. ELECTRON-BEAM PREIRRADATION AND GRAFTING OF ACRYLIC-MONOMERS ONTO EVA COPOLYMERS

An attempt has been made in the paper to impart flame retardancy to po lymers with grafting induced by the electron-beam (EB) preirradiation technique. Based on EVA copolymers with different VA contents (%), the authors have tried to use EB pre-irradiation under atmosphere followe d by grafting with/without subsequent saponification expediting the ch arring of polymers upon heating. Characterization of the flammability of the irradiated EVA copolymers grafted with acrylic monomers (MAA, A A, and AAm) indicates that this approach turns out to be promising and worth pursuing in research and/or in applications.
