Material BehaviourInfluence of flow on the global crystallization kinetics of iso-tactic polypropylene

The crystallization behavior of iso-tactic polypropylene (iPP) has been studied placing particular emphasis on the influence of flow on the global kinetics of crystallization. In order to quantify the kinetics an Avrami-type approach has been used. The results are discussed in the context of the Doi-Edwards independent alignment approximation (DE-IAA) model for flow-induced crystallization.
