Studies on the curing kinetics and thermal stability of the novel tetrafunctional epoxy resin N,N,N′N′-tetrakis(2,3-epoxypropyl)-4,4′-(1,4-phenylenedioxy)dianiline

A novel tetrafunctional epoxy resin, namely N,N,N′N′-tetrakis(2,3-epoxypropyl)-4,4′-(1,4-phenylenedioxy)dianiline, has been synthesized. The curing kinetics has been studied by differential scanning calorimetry (DSC) using various amine curing agents. Thermal stabilities of the cured products have been investigated by thermogravimetric (TG) analyses. The overall activation energies for the curing reactions are observed to be in the range 63.6–196.7 kJ·mol^–1. The cured products have good thermal stability.
