Abstract : Structure - property relations in polymers often rely on molar mass to represent the structure. While molar mass is of high importance, other features such as branching or composition are often neglected. One reason is the lack of methods as established as size-exclusion chromatography to look at branching or composition. The examples of poly(acrylic acid), chitosan and bio-sourced polyamides will be discussed, presenting characterisation using capillary electrophoresis in the critical conditions and NMR spectroscopy.
