摘要：A series of simultaneous interpenetrating polymer networks composed of epoxy resin (epoxy) and urethane acrylate resin (UAR) with different compositions were synthesized and the polymerization kinetics of both network formations was monitored by using a Fourier transform infrared spectroscopy for the potential application in the reaction injection molding process to prepare the toughened epoxy materials. It was found that during the course of synthesis the polymerization rate for formation of both pure networks has almost no dependence on the concentration of reactants, especially at the early stage of reaction and the two pairs of reactants interfere with each other significantly, although they followed different polymerization mechanisms. All these unusual polymerization kinetics behaviors observed could be correlated well with the changes of viscosity and morphology of the systems. (C) 1998 Elsevier Science Ltd. All rights reserved.
