Abstract

Curing kinetics of an epoxy resin containing 2-pyrone-4,6-dicarboxylic acid (PDC) nuclei which is obtained from lignin biodegradation intermediates was studied. Activation energy of the resin was estimated according to Kissinger and Ozawa methods. From Kamal equation, reaction constants and reaction rates were calculated. These constants were approximately coincident to those estimated from the results of in situ FT-IR measurement.
