Numerical Simulation of Crystallization Morphological Evolution under Nonisothermal Conditions

摘要

In order to obtain more information about the process of crystallization, the Monte Carlo method was used to simulate crystallization morphological evolution of semicrystalline polymers, such as isotactic polypropylene (iPP), and calculate the development of crystallinity. With remarkable progress, the morphological evolution of crystallization and development of crystallinity were obtained simultaneously during the process of the simulation. The simulated results are in good agreement with the experimental results under nonisothermal quiescent conditions when the induce time is explicitly considered during the process of simulation.
