A review of the different coextrusion processes and the related processing problems is presented. A one-dimensional bilayer coextrusion Poiseuille flow model is first developed …
Biodegradable Polymer Blends and Composites from Renewable Resources provides a comprehensive, current overview of biopolymeric blends and composites and their …
Multilayer coextrusion is a process in which polymers are extruded and joined together in a feedblock or die to form a single structure with multiple layers. These layers normally should …

The interfacial stability of coextruded polypropylene (PP) and high-density polyethylene (HDPE) has been examined experimentally in a slit-die geometry. Our experimental …
Superposed plane Poiseuille flow of an incompatible polymer system consisting of polypropylene and high‐density polyethylene has been investigated. Using the apparatus …

The stability of Hagen-Poiseuille flow of a Newtonian fluid of viscosity η in a tube of radius R surrounded by a viscoelastic medium of elasticity G and viscosity ηs occupying the annulus …
In this study, we have elucidated the molecular origin of shear banding in the entangled polymeric melts. Specifically, it is shown that the inflection point corresponding to the stress …
We have performed hi-fidelity dissipative particle dynamics (DPD) simulations of shear flow of polymeric melts in a broad range of system sizes and two entanglement densities to …
