Abstract
Estimation of thermal stability for diglycidy1 ether of bisphenol A(DGEMA)/4, 4'-methylene dianiline (MDA)/pheny1 glycidy1 ether(PGE)-acetamide(AcAm)/carboxy1-terminated acrylonitrile butadiene copolymer (CTBN) system was studied by thermogravimetry(TG) analysis. To get activation energy for thermal degradation, Freeman & Carroll, Kissinger, and Flynn & Wall expressions were used. The activation energy of Freeman & Wall expression was 112.9kj/mol, that of Kissinger expression was 151.5 kj/mol and that of Flynn & Wall was 168.3kj/mol.
Diglycidyl ether of bisphenol A(DGEBA)/4,4'-methylene dianiline(MDA)/phenyl glycidyl ether(PGE)-acetamide(AcAm)/carboxyl-terminated acrylonitrile butadiene copolymer(CTBN) 계의 열적 안정성을 평가하기 위해 열중량 분석법(TG)을 사용하였다. 활성화 에너지를 구하기 위해 Freeman & Carrol, kissinger, Flynn & Wall 식을 사용하였다. Freeman & Wall 식을 이용하여 구한 활성화 에너지는 112.9 kJ/mol, Kissinger 식에 의한 값은 151.5kJ/mol 이었으며, Flynn & Wall식에 의해 구한 값은 168.3 kJ/mol 이었다.
