The rate constants for the reaction of two aliphatic hindered amines with phenylglycidyl ether (PGE) and the diglycidyl ether of bisphenol A (DER 332) were determined by differential scanning calorimetry (DSC). The two exothermic peaks which are present in the DSC data result from the consecutive reactions of the primary and secondary amine hydrogens and allow k1 and k2 to be determined. The resulting k1/k2 ratios obtained for these hindered amine systems are larger than the ratios previously reported for unhindered amine/epoxides.
