Abstract

We studied the cure kinetics of the DGEBA(Diglycidyl ether of bisphenol A)/MDA(4, 4' -methylene dianiline)/MN(Malononitrile)/HQ(Hydroquinone) system by Barrett method and Integral method with dynamic runs of differential scanning calorimetry(DSC). Kinetic parameters such as activation energy and pre-exponential factor were obtained and reaction order was estimated roughly supposing that present system was adjusted to nth order reaction. The MN(Malononitrile) was introduced as a chain extender and HQ(Hydroquinone) as a reactive accelerator or catalyst.

DGEBA(Diglycidyl ether of bisphenol A)/MDA(4, 4' -methylene dianiline)/MN(Malononitrile)/HQ(Hydroquinone)계의 경화 반응속도론을 differential scanning calorimetry(DSC)의 승온적 방법(dynamic runs)에 의해 Barrrett method와 Integral method로 연구하였다. 활성화 에너지, pre-exponential factor와 같은 kinetic parameter들이 구하여 졌으며 반응 차수는 본계가 n차 반응 속도식에 적용된다는 가정하에 추정되었다. MN(Malononitrile)은 본 반응의 사슬 연장제로, HQ(Hydroquinone)은 반응 가속제 또는 촉매로 도입되었다.
