“…Several studies on the motions of nitroxide radicals in polymer matrix are known 1133,1208,1209,1212,1276,1347,1792,1793,1904,[2082][2083][2084][2085][2086]2220,2224,2233,2353,2484) Some of nitroxide radicals easily diffuse into various polymers 1212,2083,2085). By this method it is possible to study, using ESR spectroscopy, the mobility of the dissolved molecule in its microscopic environment.…”

“…The calculations were performed with the extinction ratios reported in [6]; the results are listed in Table 1. EPR spectroscopy was used to study the rotational mobility, which is characterized by correlation time τ с of TEMPO and BZONO radicals [3,4], in the temperature range of 293-363 K with an EPR-V radiospectrometer. The elastomers were saturated with TEMPO from the gas phase at room temperature for three days.…”

“…In most cases, they were mostly composed of isomeric butadiene units of one kind (cis-1,4 in PBs or trans-1,4 in NBRs) ( Table 1). The temperature dependence of the rotational mobility of free-radical probes with different dimensions (2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO) and 4-benzoate-2,2,6,6-tetramethyl-1-piperidinyloxy (BZONO)) in these elastomers was investigated [3,4].…”

“…Величину A zz определяли экспериментально из ЭПР-спектров нитроксильного радикала, находящегося в полимере, при -216°C; она не сильно отличалась от значения, приведенного в [26]. Значения времени корреляции вращения зонда τ в области быстрых вращений (5 · 10 -11 < τ < 10 -9 с) находили из спектров ЭПР по формуле [27]: τ = ΔН + × [(I + /I -) 0.5 -1]6.65 × 10 -10 ,…”
