Spin Label and Spin Probe Studies of Synthetic Polymers

  • G. Gordon Cameron

Chapter

Summary

Stable nitroxide radicals are now widely employed as spin labels and spin probes for studies of the relaxations and dynamics of synthetic polymers. For the spin label experiment the nitroxide radical is covalently bound to the polymer chain and for the spin probe experiment a small nitroxide molecule is dispersed in the polymer matrix. Methods of preparing spin probes and spin labelled polymers are reviewed briefly in this chapter. The electron spin resonance (ESR) spectra of the probed or labelled polymers are sensitive to motions in the time regime 10−3−10−11 s and methods for extracting this information are described. The scope and limitations of the spin label and probe techniques are illustrated by reference to published work on synthetic polymers in bulk and in solution.
