The effect of zeolite on the curing of epoxy resin by polyaniline: A kinetic study

Polyaniline sulfate-zeolite composite was prepared by emulsion polymerization. Epoxy resin was cured using polyaniline-sulfate salt and various amounts of polyaniline sulfate-zeolite composite. The kinetics of the cure reaction for an epoxy resin based on the diglycidyl ether of bisphenol A (DGEBA) with polyaniline-sulfate and polyaniline sulfate-zeolite composite have been studied using differential scanning calorimetry (DSC) under isothermal and dynamic conditions. Isothermal kinetics analysis was performed using the phenomenological model of Kamal. Dynamic kinetic analysis was performed using Kissinger's method. Copyright (C) 2002 John Wiley Sons, Ltd.
