中文摘要：

以1,3-二（4-羟基苯基）金刚烷（BHPA）和环氧氯丙烷（ECH）为原料,采用二步法合成了低分子量的1,3-二（4-羟基苯基）金刚烷二缩水甘油醚（DGEBAD）,采用 FTIR、1 H-NMR和凝胶渗透色谱（GPC）分别对其结构和分子量进行了表征并滴定得到其环氧值；采用旋转流变仪对其流变性能进行了表征。使用4,4’-二氨基二苯基甲烷（DDM）固化DGEBAD,对固化DGEBAD-DDM树脂体系的力学性能、吸水率和耐热性进行了测试,得到的固化物的拉伸强度为90 MPa,玻璃化转变温度为163℃,5%热失重温度高达401℃,吸水率比相同条件下环氧树脂 E51-DDM固化物降低了31.60%。

英文摘要：

The diglycidyl ether of 1,3-bis （4-hydroxyphenyl）adamantane（DGEBAD）with low molecular weight was synthesized from 1,3-bis （4-hydroxyphenyl）adamantane （BHPA）and epichlorohydrin （ECH）by two-step method.The structure and molecular weight were confirmed by FTIR,1 H-NMR and gel permeation chromatogra-phy（GPC）,and epoxy value was obtained by titration.The rheology property was also characterized by rotational rheometer.DGEBAD was cured with 4,4’-diaminodiphenyl methane （DDM）.The mechanical properties,water ab-sorption rate and heat resistance characteristics of the cured DGEBAD-DDM resin system were investigated.The tensile strength and the glass transition temperature of the cured DGEBAD-DDM resin system is 90 MPa and 163 ℃,respectively and 5% mass loss temperature occurs at up to 401 ℃.The water absorption rate of the cured DGEBAD-DDM decreases by 31.60% compared to the cured epoxy resin E51-DDM.
