The curing kinetics and the glass transition behavior of amino‐polycarbonate with diglycidyl ether of bisphenol‐A epoxy resin systems were studied by differential scanning calorimetry (DSC). The ASTM E‐698 method was chosen to determine the kinetics parameters of the curing reaction, including the activation energy, preexponential factor, rate constant, and 60‐min half‐life temperature. The amino‐polycarbonate was able to accelerate the curing reaction, reduce the apparent active energy, and decrease T g of the systems. A homogeneous amino‐polycarbonate/epoxy resin network was observed in scanning electron microscopy (SEM) pictures. © 2001 John Wiley & Sons, Inc. J Appl Polym Sci 82: 833–838, 2001
