摘要
In polymer processing, structure development is a key issue in mastering the final properties of the products. In this paper, a general differential system for 2D and 3D quiescent conditions was adopted to describe the crystallization evolution, and the simulation of the crystallization evolution was implemented by the Runge-Kutta method using Matlab. The transformed volume fraction and the number of activated nuclei in 2D were also obtained by crystallization experiments. The crystallization kinetic parameters were determined and optimized by the inverse genetic algorithms method based on the experimental results. The experimental and simulation results of the transformed volume fraction and the number of activated nuclei in the 2D condition were in good agreement. The crystallization model and the crystallization kinetic parameters were used to predict the morphological evolution of isotactic polypropylenes (iPP) and the results were analyzed.
