Abstract
Recently epoxy resin compositions having backbone of novolac derivatives with biphenylene compounds have been used as materials of eco-freindly EMC (Epoxy Molding Compound), because the cured epoxy resin compositions show the self-extinguishing without flame retardant additives. In this study, epoxy resin compositions were prepared and cured using novolac derivateves with biphenylene. Their propeties - structures of phenol derivatives and reactivity, thermal expansion, modulus, and thermal degradation - were obtained by DSC, DMA, TMA, TGA method. When both epoxy resin and hardenr had the biphenyl novolac structure, epoxy resin compositions showed low thermal expansion, good mechanical property, and combustion retardation.
