Monte Carlo Simulation of Crystalline Morphology Under Temperature Gradient: A Case Study of Syndiotactic Polypropylene

摘要

In this work, a mathematical model for describing the crystallization kinetics and morphological development of syndiotactic polypropylene (s-PP) during crystallization under temperature gradient is developed based on Monte Carlo simulation. The effect of temperature range is also investigated. The results shows that temperature range significantly affected the relative crystallinity, average crystallite size, and crystallite size distribution. The average Avrami rate constant is found to be adequate for describing the overall crystallization rate at the early state of crystallization.
