Abstract
The dynamics and stability of film casting process including crystallization kinetics have been investigated using a 2-D model with finite element method (FEM). The transient solutions of extensional deformation processes such as film casting, film blowing and fiber spinning are essential for the comprehensive analysis of their dynamics, but they are found extremely difficult to obtain if flowinduced crystallization (FIC) occurs, while it is rather a simple exercise without it. Once the transient solutions of film casting process with flow-induced crystallization were obtained, the information on this transient behavior becomes extremely useful for the optimization and stabilization of the process. Experimental corroboration using isotactic polypropylene (iPP) has been achieved.
