摘要：

Different isolated or competitive mechanisms have been experimentally observed in order to predict the kinetics of an epoxy—amine reaction in terms of various mathematical models based on different possibilities of reaction. Impurities such as water, glycols, and in general all donors of active hydrogen even at low concentrations significantly change the course of the reaction. We therefore decided to study the curing reaction of the epoxy resin, first as a commercial product and later purified, with m‐xylylenediamine of known purity. The extent of cure has been followed and determined by differential scanning calorimetry (DSC) and infrared spectroscopy (FT‐IR). Purity, epoxy content and OH content were measured by liquid chromatography HPLC and wet analysis. Copyright © 1990 John Wiley & Sons, Inc.
