Abstract
The EPR spectra of several nitroxide biradicals derived from substituted bis(hydroxy‐ureas) have been determined. The main differences in these spectra arose dur to intramolecular interaction of the nitroxide groups. Interaction was only observed for the case where the nitroxide group was bonded to an aliphatic group.

Four series of poly(o-hydroxy amide)s were prepared by the low-temperature solution polycondensation of the bis(ether benzoyl chloride)s extended from hydroquinone and its methyl-, tert-butyl-, or phenyl-substituted derivatives with three bis(o-aminophenol)s. Most of the poly(o-hydroxy amide)s displ
