Abstract

ABSTRACT: High performance epoxy resins have attracted much research interest in the last decades. Herein, two novel epoxy monomers containing cycloaliphatic hydrocarbon, 1, 4‐bis(4‐( N, N ‐diglycidylamino)phenoxy)cyclohexane (CyhEP) and 1, 3‐bis(4‐( N, N ‐diglycidylamino)phenoxy)adamantane (AdaEP) were synthesized and characterized. They were cured with 4‐methylhexahydrophthalic anhydride (MHHPA) to prepare the highly crosslinked thermosets. Both epoxy resins show good thermal stability ( Td 5 > 300 °C), high glass transition temperature (> 200 °C), and high storage modulus (> 3.2 GPa) due to their highly crosslinked structure. The AdaEP/MHHPA resin shows a low dielectric constant (3.4 at 1 MHz) because of the introduction of bulky rigid adamantane into the polymer. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.
