The Kinetics of Polymer Cure by Differential Scanning Calorimetry. Volume I

Abstract

The need for providing processing information for new resins requires obtaining the reaction kinetics for polymerization of these resins. The kinetic parameters can be used to generate reaction window plots. Because of the exothermic nature of these reactions, differential scanning calorimetry (DSC) was utilized to obtain the kinetic parameters. Multiple-scan DSC curves at several heating rates were utilized applying the Friedman method of kinetic analysis. This method, which contains activation energies at each extent of conversion, allows kinetic parameters to be evaluated without having to assume any apriori functionality for the rate dependency. The kinetic parameters so obtained are then utilized to predict the behavior of reacting systems under a variety of isothermal conditions. This behavior is displayed in reaction window plots. The method is described, and includes descriptions of computer programs with illustrated data from the cure of new resins.
