摘　　要：以1,2-丙二醇(PDO)或二甘醇(DEG)为溶剂,将工业副产物尼龙酸(NA)及活性炭按一定比例混合,氮气保护下加热搅拌、溶解、经过一定时间后,趁热过滤得到近无色的尼龙酸二元醇溶液。再以所得溶液为主要原料,经酯化、缩聚等反应,合成了一系列环保型的尼龙酸聚酯增塑剂,利用核磁共振(1H-NMR、13C-NMR)和凝胶渗透色谱(GPC)等手段对所得增塑剂进行了表征。结果表明,利用该方法可方便、经济、高效地合成尼龙酸聚酯类增塑剂。Abstract： The protection of nitrogen, 1, 2-propanediol （PDO） or diethylene glycol （DEG） was as solvent to dissolve nylon acid （NA） at a certain ratio. After stirred at appropriate temperature for hours, the mixed system was filtered and obtained a light-colored solution. Then, polyester plasticizer was successfully synthesized from this mixed liquid with further esterification reaction and condensation polymerization. The obtained product was characterized by 1H-NMR, 13C-NMR, GPC etc. The results indicated that the method was not only a convenient system, but also a efficient economical one.
