Abstract: | The use of chromatographic stationary phases or solvent modifiers to modulate diffusion properties in NMR experiments is now well established. Their use can be to improve resolution in the diffusion domain or to provide an insight into analyte–modifier interactions and, hence, the chromatography process. Here, we extend previous work using size‐exclusion chromatographic stationary phases to the investigation of polymer mixtures. We demonstrate that similar diffusion modulation behaviour is observed with a size‐exclusion chromatographic stationary phase that can be understood in terms of size‐exclusion behaviour.
