Low k epoxy resin containing cycloaliphatic hydrocarbon with high crosslinking density

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 synt...

Zusammenfassung: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 (Td5 > 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.
