摘要：

The self-diffusion in solutions of polystyrene in toluene with similar concentrations and molar masses was studied. The pulse-field gradient nuclear magnetic resonance self-diffusion measurements cannot detect cluster diffusion in solutions of polystyrene in toluene. There was also no indications of cluster diffusion in polyelectrolyte solutions.
