A spin-labeled copolymer of styrene was synthesized and its ESR spectra in dilute toluene solution were obtained. Polystyrene segmental rotational diffusion in toluene solution over a broad temperature range were characterized using a model of microscopic order but macroscopic disorder. Activation energy obtained was is in a good agreement with recent fluorescence results.
