Abstract
Naphthalene containing aralkyl novolac epoxy resins were synthesized by the condensation of p-xylylene glycol with 2,7-dihydroxynaphthalene or 2-naphthol followed by the epoxidation of the resulting aralkyl novolacs with epichlorohydrin. The mechanical and dynamic viscoelastic properties of cured aralkyl novolac epoxy resins were investigated. Comparisons of mono- and di-functional naphthalene containing aralkyl novolac epoxy resins based on thermal and moisture absorption properties were also studied. The results indicate that a naphthalene containing aralkyl epoxy resin made from the difunctional naphthol has a low coefficient of thermal expansion, high heat resistance, and low moisture absorption.
