Degradation of High Molar Mass Polymers

Polymer Degradation

The degradation of high molar mass polymers is known to occur in an extensional flow field, in which polymer chains elongate and become susceptible to mid-point scission. In this application note, we used SEC coupled with a DAWN® or miniDAWN® multi-angle light scattering (MALS) detector to analyze the polymer molar mass distribution and obtain the absolute Mw and PDI.
