Abstract
The method of Calvet microcalorimetry was used to follow
the course of the spontaneous polymerization of styrene. Comparison
of this method with widely used point-by-point methods has been
performed and the great advantages of calorimetry are shown.
Calorimetry measures continuously and directly the reaction rate
independently from the physical state of the sample using only one
sample for the whole conversion range. The accuracy and sen,sitivity
achieved are better than those achieved with other methods. On the
basis of these advantages Calvet microcalorimetry can be recommended
as very promising method for the investigation of polymerization
kinetics.
