= Polymer fractionation
{wiki=Polymer_fractionation}
Polymer fractionation is a process used to separate a polymer sample into fractions based on the molecular weight or size of the polymer chains. This technique is important in the study and application of polymers, as different fractions may exhibit distinct physical, chemical, and mechanical properties due to variations in molecular weight or chain architecture. There are several methods of polymer fractionation, including: 1. **Size Exclusion Chromatography (SEC)**: This technique separates polymers based on their hydrodynamic volume.
