Abstract

Incorporating spirobisindane into the molecular structure of epoxy polymers has shown to reduce the coefficient of thermal expansion. This reduction is due to the highly rigid and twisted structure which restricts the mobility of molecular chains. A spirobisindane-based epoxy has been synthesized and characterized using IR, 1H NMR and 13CNMR spectroscopy. In addition, varying amounts of the spirobisindane-based epoxy have been polymerized with an amine curing agent. The coefficient of thermal expansion, glass transition temperatures and moduli will be given and compared to the original epoxy system.
