## Abstract Extending our earlier measurements of homopolymer thermal diffusion, we characterize here the thermal diffusion of nine copolymers in toluene by thermal fieldβflow fractionation (thermal FFF). The copolymers are organized into groups whose members differ in one major aspect only. These
## Abstract Thermal fieldβflow fractionation (ThFFF) is a new elutionβbased separation method for determining molecular weight distributions of polymers. Calibration can be achieved using monodisperse standards of the specific polymer of interest. In order to expand the range of polymer types for w
