Adamantane type epoxy resin and method for preparing the same
By combining the condensation and epoxidation reactions of adamantane compounds and phenolic compounds with crosslinking polymerization using a specific curing agent, the problems of uneven dispersion and low crosslinking density of adamantane epoxy resins have been solved, resulting in the preparation of adamantane-type epoxy resins with high heat resistance and low dielectric properties, suitable for high-frequency communication and advanced microelectronic packaging.

Abstract
本发明公开了一种金刚烷型环氧树脂及其制备方法，属于环氧树脂合成技术领域，以金刚烷类化合物与苯酚类化合物为原料，在酸性催化剂作用下进行缩合反应，生成金刚烷‑双酚中间体。将金刚烷‑双酚中间体与环氧氯丙烷在相转移催化剂进行环氧化反应，再与碱催化下进行闭环反应，得到金刚烷型环氧单体。在固化剂作用下，金刚烷型环氧单体进行交联聚合，得到金刚烷型环氧树脂。本发明在环氧树脂中引入金刚烷独特的空心笼状结构，再采用固化剂固化后，既表现出超高玻璃化转变温度与高储能模量，又凭借金刚烷的低极化特性与固化剂中的‑CF3基团的超低介电贡献，实现低介电常数与低介电损耗。
