摘　　要：以2,6-二甲基苯酚和2,2-双(4-羟基-3,5-二甲基苯基)丙烷为原料,催化合成低分子量双端羟基聚苯醚,采用凝胶渗透色谱、傅里叶变换红外光谱和核磁共振氢谱对产物结构进行表征。以氰酸酯树脂为固化剂,合成聚苯醚/氰酸酯树脂复合材料,研究不同双端羟基聚苯醚添加量对复合材料性能的影响。结果表明,双端羟基聚苯醚的引入,提高了材料的力学性能和低介电性能。采用非等温DSC法研究了双端羟基聚苯醚/氰酸酯树脂体系的固化动力学,利用Kissinger、Starink等方法对活化能进行计算,并得到了固化过程的动力学方程,且拟合曲线与实验数据拟合程度较好。低分子量双端羟基聚苯醚有望成为高性能覆铜板的一种理想热固性树脂材料。Low molecular weight polyphenylene oxide with double terminal hydroxy was synthesized from 2,6-dimethylphenol and 2,2-bis(4-hydroxy-3,5-dimethylphenyl)and confirmed by GPC,FTIR and 1HNMR.The effect of different amounts of polyphenylene ether on the polyphenylene ether/cyanate ester resin composite materials was studied.The results showed that the introduction of polyphenylene ether improved the mechanical properties and low dielectric properties of the material.The curing kinetics of the double terminal hydroxyphenylene ether/cyanate ester resin system was studied by using non isothermal DSC method.The activation energy was calculated by using Kissinger,Starink and other methods,and the kinetic equation of the curing process was obtained.The fitting curve was well matched with the experimental data.Low molecular weight polyphenylene etherwith double terminal hydroxyl is expected to become an ideal thermosetting resin material for high-performance copper-clad laminates.
