等离子体接枝EVA共聚物薄膜阻燃性能的研究与表征

APPROACHES AND CHARACTERIZATION TO THE FLAME RETARDANCY OF POLYMERS BY PLASMA TREATMENT AND GRAFTING OF ACRYLIC MONOMERS ONTO EVA COPOLYMERS

以不同 Ｖ Ａ 含量的 Ｅ Ｖ Ａ 共聚物为基础，尝试通过等离子体接枝方法接枝甲基丙烯酸、丙烯酸和丙烯酰胺促进聚合物热降解成炭性能，以达到聚合物阻燃的目的并对其燃烧性能作了全面的表征。本工作表明等离子体接枝确是一个值得研究和开发的新型阻燃途径，文献中尚未见到有关报导。

An attempt has been made in the paper aiming at imparting flame retardancy to polymers with grafting induced by plasma. Based on EVA copolymers with different VA contents(%) the authors have tried to use the Ar plasma followed by grafting with/without subsequent saponification expediting the charring of polymers upon heating. Characterization of the flammability of the plasma treated EVA copolymers grafted with acrylic monomers(MAA, AA and AAm) indicates that this approach turns out to be a promising way and worthy doing whatever in research and/or in applications.
