The influence of the dynamics of the polymer materials crystallization process on its properties was investigated. The crystallization process was studied in two cases: during supercooling, and during supercooling together with applied shear stress. The impact of shear stress and supercooling on the crystallization kinetics was studied. The experiment was carried out using two techniques: differential scanning calorimetry and rheometry. Polyamide-12 was chosen as the object of research. The data were processed by the method developed by the authors. The following parameters were determined: induction period, rates of nucleation and growth.
