Abstract
Several spin-labeled car☐yl-containing resins were prepared, containing different concentrations of spin labels (nitroxyl or verdazyl stable free radicals). ESR studies of the prepared resin specimens demonstrated that the dependence between their ESR signal area and estimated and/or calculated amount of attached spin labels is linear in the case of verdazyl radicals, which makes this non-destructive approach a promising fast and accurate method for a resin loading determination.
