Influence Of The Temperature On Flow-Induced Crystallization Of Isotactic Polypropylene And Propylene-Ethylene Random Copolymer, Hugo Boitout
Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research
When flow is applied on a semi-crystalline polymer melt, it can greatly impact how it crystallizes its final properties. Therefore, it is crucial to understand the basic mechanism of flow induced crystallization (FIC). Only then will it be possible to predict final properties from the type of resin and processing conditions. Polypropylene is one of the most widely used polymers. Its processing generally involves subjecting the melt to intense flow fields, so FIC commonly occurs.
This study investigates the influence of temperature of shear and crystallization on the FIC behavior of isotactic polypropylene (iPP). Temperature is one of the main …
