About this document
Viscosity and Elasticity of Polymer Melts by Ali Hassan is a document available to read on EtoBox.
The document discusses viscosity and mechanical properties of polymer melts and their dependence on molecular weight and temperature. It explains that the viscosity of entangled polymer melts increases with molecular weight above the entanglement molecular weight according to a power law. It also describes the time-temperature superposition principle which allows constructing complete relaxation curves using temperature shift factors. Equations like the Williams-Landel-Ferry and Vogel-Fulcher-Tammann equati
