摘　　要：PEN用甲醇醇解,生成的萘二甲酸二甲酯过滤除去,解离出的DEG用气相色谱法测定。The poly(ethylene-2, 6 naphthalate) is degraded by methol, alcoholysis product-dimethol naphthalene 2, 6-dicarboxylate is filtered off from solution, the diethylene glycol(DEG) in PEN is remained in the solution and determined by Gas chromatograph

关 键 词：聚2 6-萘二甲酸乙二酯 气相色谱 醇解 二甘醇
