摘要: 以乙烯-醋酸乙烯共聚物通过等离子体接枝丙烯酸以达到阻燃的目的。接技后样品的点燃时间延长、极取氧指数提高、成炭量增加,说明接枝后的侧基(-COOH,-COONa和-COOK)在热降解过程中不仅知身参与成炭,而且强有力地促进了基体聚合物的成炭过程。Abstract: An attempt has been made in this study to render polymers flame retardancy by a grafting method induced by plasma. Based on ethylene-vinyl acetate (EVA) copolymer grafted with acrylic acid, it was found that the time to ignition of the grafted sample was
