Model Free Kinetics and Vitrification During Curing

To investigate the influence of vitrification on the results of the MFK analysis of heating curves. As shown in Volume 1 and Section 4.1.5, the kinetics of a curing reaction can be described using model free kinetics (MFK). MFK can then be used to make predictions about the course of the reaction. If the material vitrifies during the measurement, there is a significant decrease in the reaction rate and hence a change in the kinetics.
