About this document
GPC Analysis of Polymer Degradation by SophiaGR is a document available to read on EtoBox.
This document discusses the interpretation of molecular weight distribution (MWD) data from gel permeation chromatography (GPC) to understand polymer degradation mechanisms. It presents a case study of ultrasonic degradation of polystyrene solutions. By comparing calculated MWDs from different degradation schemes to experimental data, the authors determined that multiple fragmentation best explained the results. This indicates ultrasonic degradation involves multiple bond scissions per macromolecule. Spectr
