摘要
叙述了PEN及其中间体2,6-萘二甲酸的发展情况。介绍了PEN的一般特性,如具有较高的气体阻隔性,较好的耐热性,优良的力学性能,良好的光学性能,稳定的化学性能及其在瓶、薄膜方面的应用。指出制约PEN发展的关键因素是其中间体2,6-萘二甲酸的生产。并介绍了2,6-萘二甲酸的制备方法。
The development of polyethylene naphthalate （PEN） and its intermediate 2,6-naphthalene dicarboxylic aied （2,6-NDA） is reviewed. The normal characteristics of PEN such as the better gas barrier performance, heat stability, good mechanical properties, optical characteristics, steady chemical properties and the application of PEN to bottle and film field were introduced. It was pointed out that the key factor that restrict the development of PEN was the production of its intermediate 2,6-naphthalene diearboxylie acid （2,6-NDA）. The preparation methods of 2,6-NDA were also introduced.
