Identification of parameters in polymer crystallization Original Research Article

The complex phenomenon of partial crystallization of polymers is examined. A mathematical model is exploited for the isothermal crystallization process in which the nucleation rate and the growth of the spherulites are constant. This model consists of an integro-differential equation, depending on some key parameters, whose identification is crucial for a correct description of the phenomenon. The main purpose of this work is to solve this problem numerically, using the experimental data provided by the HIMONT-ITALIA Laboratories. An error analysis of the adopted numerical method is carried out, and some numerical results are given, to show the validity and flexibility of the technique.
