ESR relaxation measurements were carried out for a dilute toluene solution of in-chain-labeled polystyrene containing double bond in the main chain next to the spin label. The temperature was varied from -20 to +93 °C. It was found that the correlation time is larger by an order of magnitude than that of the unlabeled polystyrene, which can be explained by the influence of double bond on the segmental motion. The number of monomer units involved in the ESR relaxation process was estimated as 2–4. The preparation of spin-labeled polystyrene copolymer was also described.
