Study of dynamic crystallization kinetics of a thermotropic liquid crystalline polyester with flexible spacer in the main chain

The study of dynamic crystallization kinetics of a thermotropic polyester with flexible spacers in the main chain was done. The aim of this study was to verify the crystallization kinetics mechanism of a thermotropic semi-flexible polyester by a dynamic method. The selected method (Ozawa method) has allowed to describe the crystallization kinetics and the values of n (Avrami exponent) correspond to sheaf-like aggregation without further growing into spherulites.
