Present Challenges in the Numerical Modeling of Polymer-forming Processes
ABSTRACT The purpose of the present paper is to present an overview of the main progresses recently made in the numerical modeling of polymer-forming processes and to describe the challenges to overcome in the near future. Examples are presented in different domains, such as die extrusion, injection molding, film processing, reactive extrusion and pipe reinforcement.

ABSTRACT: In order to deal with the complicated relationships among the variables of the reactive extrusion process for activated anionic polymerization, a three-dimensional equivalent model of closely intermeshing co-rotating twin screw extruders was established. Then the numerical computation expressions of the monomer concentration, the monomer conversion, the average molecular weight and the fluid viscosity were deduced, and the numerical simulation of the reactive extrusion process of styrene was carried out. At last, our simulated results were compared with Michaeli's simulated results and experimental results.Journal of Materials Processing Technology 04/2008; 199(s 1–3):56–63.
