Thermal decomposition of a system consisting of epoxy resins and butadiene-acrylonitrile rubber

with blocked carboxyl endgroups (in English)

Summary

The rate of thermal decomposition and the kinetic parameters for diglycidyl ether of bisphenol A (DGEBA)/4,4'-methylene dianiline (MDA)/MDA-endcapped carboxyl terminated butadiene acrylonitrile rubber (CTBN) system were investigated using the data of thermogravimetric (TG) and derivative thermogravimetric (DTG) analyses and the Kissinger and Flynn & Wall expressions. The rate constant of thermal decomposition was decreased and the activation energy increased by the addition of MDA-endcapped CTBN. It means that the thermal stability of the DGEBA/MDA system was improved by the MDA-endcapped CTBN.


Keywords: epoxy resin/butadiene – acrylonitrile rubber system, activation energy of thermal decomposition, rate constants of thermal decomposition
