Abstract
The investigation of cure kinetics of biphenyl-type epoxy(4,4-diglycidyloxy-3,3, 5,5-tetramethyl biphenyl)/phenol novolac resin system with triphenylphosphine catalyst was performed by differential scanning calorimeter using an isothermal approach. The cure reaction of the system could be explained by considering the formation of epoxy-phenol-catalyst trimolecular active complex and effectively described by combining autocatalytic and nth order model. To describe the cure reaction in the latter stage, a diffusion factor has been used. By combining the proposed kinetic model with a diffusion factor, it is possible to predict the cure kinetics over the whole range of conversion.

Triphenylphosphine 촉매하에서의 biphenyl계 에폭시/페놀 노볼락 수지 시스템의 경화 반응 속도식을 등온 경화 조건에서 시차주사열량계를 이용하여 분석하였다. 본 연구의 에폭시 수지 시스템의 경화 반응은 에폭시-페놀-촉매 3분자의 반응으로 형서된 active complex의 형성을 고려함으로써 설명할 수 있었으며, 자체촉매 반응과 n차 반응 모델을 조합함으로써 효과적으로 예측할 수 있었다. 반응 후반의 경화 반응을 설명하기 위해서 제안된 화학 반응 모델에 확산 인자를 도입하였으며, 이로부터 모든 에폭시 전화 영역에서의 반응 속도를 예측할 수 있었다.
