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