Sažetak
A kinetic study of cure kinetics of epoxy resin based on a diglycidyl ether of Bisphenol A (DGEBA), with poly(oxypropylene) diamine (Jeffamine D230) as a curing agent, was performed by means of differential scanning calorimetry (DSC). Isothermal DSC characterisations of stoichiometric and sub-stoichiometric mixtures (30 phr and 20 phr of Jeffamine D230, respectively) were performed at different temperatures. Dynamic DSC characterisation of the systems was performed at heating rates of 5 and 10 Kmin-1. The kinetics of cure was described successfully by empirical models in wide temperature range. System with sub- stoichiometric content of amine showed evidence of two separate reactions, second of which was presumed to be etherification reaction. The vitrification phenomenon was successfully described by the maximum fractional conversion at a given temperature of isothermal cure. Catalytic influence of hydroxyl groups formed by epoxy-amine addition was determined. The results are in good agreement with the literature data.
