摘　　要：采用普通市售128环氧树脂经过分子蒸馏,去除轻馏分和多聚体重组分后,得到双酚A分子环氧树脂,牌号为JF-9955A。通过红外光谱和液相色谱分析,基础性能和Na+含量检测以及对其酸酐固化物性能的测试将JF-9955A与国外陶氏化学的DER 332、BakeliteEPR 162高纯度双酚A环氧树脂进行了对比。结果表明,JF-9955A具有粘度低,纯度高,可水解氯及其他离子杂质含量低等特点,各项性能指标达到国外同类产品水平。The bisphenol A epoxy resin with trademark JF -9955A was obtained by the molecular distillation of common commercial 128 epoxy resin removed the ligtht distillate and polymer heavy distillate. The JF -9955A was compared with Dow DER 332 and Bakelite EPR 162 high purity bisphenol A epoxy resins by the analysis of FT - IR and liquid chromatography, testings of basic properties and Na ＋ content detection. The product properties of the three epoxy resins cured with anhydride were also tested. The results showed that JF - 9955A had low viscosity, high purity, low contents of hydrolyzable chlorine and other ions. The performance indicators of JF -9955A reached the level of similar foreign products.
