Abstract
Synthetic polymers have complex molecular structures with distributions in molar mass, chemical composition, functionality and molecular topology. For the comprehensive analysis of polymer structures, a number of advanced spectroscopic and fractionation techniques are used. For the fractionation of polymers, most frequently column-based methods are applied. These are of limited value for the separation of very high molar mass and fragile analytes. Thermal field-flow fractionation (ThFFF) as a channel-based method has developed into a powerful alternative and complementary technique to column-based fractionations. This perspective discusses novel applications of ThFFF and highlights its potential for the fractionation of polymer assemblies such as micelles, vesicles and nanogels.
