Abstract
The one-to-one relationship between the glass transition temperature and the extent of reaction oi biphenyl-type epoxy/phenol novolac resin system was interpreted by using DiBenedetto''s equation and DiMarzio''s equation modified by Hale. The relationship between the glass transition temperature and curing time was investigated by diffusion-controlled cure kinetic equation and Hale''s equation. By combining these two equations, it was possible to construct the time-temperature-transformation (TTT) isothermal cure diagram.

Biphenyl계 에폭시/phenol novolac 수지 조성물의 유리전이온도와 전화량과의 일대일 관계를 DiBenedetto 방정식과 Hale에 의하여 보완된 DiMarzio 방정식을 이용하여 해석하였다. 경화시간과 유리전이온도와의 관계는 확산-억제된 경화반응 속도식과 Hale의 방정식으로부터 규명하였으며 이 두 식으로부터 biphenyl계 에폭시/phenol novolac 수지 조성물의 시간-온도-변태 등온 도표를 구할 수 있었다.

Keywords: biphenyl-type epoxy; phenol novolac; glass transition temperature; diffusion; cure kinetics
