摘要

IN an ordinary way the grafting induced by electron and gamma preirradiations widely used for improving the compatibility of polymers in composites gives rise to an enhancement of their mechanical properties. However, very few have been reported in the flame retardancy of polymers using these sorts of techniques. Wilkie investigated the flame retardancy of photo-initiation grafted polymers. An attempt is made in this paper to try to use the EB preirradiation on EVA copolymers with different VA contents and the subsequent grafting with saponifica-tion under atmosphere and to expedite the charring of polymers upon heating. Characterization of the flammability of the preirradiated EVA copolymers grafted with acrylic monomers indicates that this approach turns out to be a promising way and worthy of doing.
