Abstract
We have studied the curing of epoxy resin diglycidylether of bisphenol A (DGEBA), by two different hardeners poly(styrene-co-acrylic acid) (SAAx) at different acid percent and poly(acrylic acid). We follow the kinetics by non-isothermal and isothermal. In non-isothermal mode the heating rates were between 2.5 and 20°C min-1 in the temperature range of 25-250°C. The reaction was supposed to follow the n th order. In isothermal mode, four temperatures for each system were done. In this case the reaction was autocatalysed. The interpretation of the exotherms allowed to determine the kinetic parameters of the studied systems.
