Abstract
A chemorheological study of biphenyl-type epoxy/phenol novolac system was performed at different isothermal curing temperatures. To predict the chemoviscosity during isothermal curing reaction. modified Willians-Landel-Ferry (WLF) equation was used. Glass transition temperature change due to curing reaction measured by DSC could be expressed as a function of conversion. From the measurements of isothermal viscosity, C1 and C2 in WLF equation were found to have an Arrhenius-type dependence on temperature. By using these relations in conjunction with modified WLF equation, good agreement between predicted and experimental viscosity was observed.

등온경화조건에서 biphenyl계 에폭시/phenol novolac 수지 조성물의 호학레올로지 연구를 수행하였다. 등온경화반응에 따른 점도의 변화를 예측하기 위해 modified Wiliams-L뭉디-Ferry (WLF)식을 이용하였다. DSC 측정으로부터 경화반응에 따른 유리전이온도의 변화를 전환량의 함수로 표현할 수 있었다. 등온경화반응에 따라 측정된 점도의 변화를 이용하여 WLF식에서의 C1, C21, C2

Keywords: chemorheology; biphenyl-type epoxy/phenol novolac system; modified Williams-Landel-Ferry (WLF) equation; glass transition temperature
