摘　　要：介绍了乙烯-乙烯醇共聚物(EVOH)的性能、用途、生产技术及发展前景。EVOH由于其高阻隔性能且环保无毒,被广泛应用于包装领域。EVOH树脂的合成主要是将乙烯与醋酸乙烯通过聚合反应得到聚合物,聚合物再经过皂化反应制得EVOH。国内目前EVOH树脂供需矛盾突出,市场空间巨大,国内企业需加速开发EVOH生产技术,早日实现国产化。The properties,applications,production technology and development prospects of ethylene-vinyl alcohol copolymer(EVOH)were introduced.EVOH is widely used in packaging field because of its high barrier performance and environmental protection and non-toxicity.EVOH resin is mainly synthesized by the polymerization of ethylene and vinyl acetate,and then the polymer is saponified to produce EVOH.At present,there is no EVOH resin manufacturer in China.The contradiction between supply and demand is prominent and the market space is huge.Domestic enterprises need to speed up the development of EVOH production technology and realize localization as soon as possible.

关 键 词：乙烯-乙烯醇共聚物 高阻隔性能 包装 国产化
