Polymer Rheology - an overview | ScienceDirect Topics
Polymer rheology is the scientific study of how polymeric fluids deform when subjected to external stresses. When synthesizing a polymer for a particular application, an understanding of the extruder environment in which that polymer will be used is the key to determining the properties of the polymer, so that its response matches the ...
For both the layperson and the technical person, rheology is a set of problems or observations related to how the stress in a material or force applied to a material is related to deformation (change of shape) of the material. What is rheology anyway? do we reach these goals? How? 1. Conservation laws. 2. Mathematics. 3.
