Computer Modeling and Simulation for 3D Crystallization of Polymers. II. Non-Isothermal Case

Abstract

A 3D computer modeling and simulation has been used to predict crystallization kinetics and crystal morphology in polymers under the non-isothermal condition. A parametric study is used to explore the influences of thermal conditions on the crystallization. The results indicate that cooling rate has a strong impact on the crystallization kinetics as well as the morphology. The initial temperature only affects the crystallization kinetics and has no impact on the final morphology. It is observed that the distribution of spherulite size in non-isothermal case is much broader than that in the isothermal case.
