Investigation of curing kinetics of the epoxy resin modified by CO2 fixation reaction using advanced integral isoconversional method

Curing kinetic of epoxy resin by CO2 fixation reaction has been investigated. CO2 fixed modified epoxy resin (CFME) was synthesized at different amounts of carbonation content under ambient condition. The dependence of activation energy, pre-exponential factor and reaction model on the extent of conversion have been calculated in the tabular form using advanced integral isoconversional method. A great change observed in the cure kinetic parameters of CO2 fixed modified epoxy resin could be attributed to the formation of 1,3-dioxolane-2-one rings, which synthesized through CO2 fixation reaction
