摘要：

In the present work, the kinetics of the reaction of p-tolyl isocyanate with a polycarbonate diol has been studied, as a model for similar urethane systems. Liquid chromatography has been used to monitor the reaction, which allows direct measurement of the reaction of isocyanate group. The results obtained have enabled us to propose a reaction path and an autocatalyzed third-order kinetic model. Activation energy values have been determined from measurements taken at different isothermal temperatures. (C) 1999 Elsevier Science Ltd. All rights reserved.
