Abstract:<\/p>\n

The influence of phenalenone dyes of different structure and reactivity on the mobility of macrochains of crosslinked polyurethanes was studied using EPR method with nitroxyl paramagnetic probe. The polyurethanes were synthesized using aliphatic diisocyanate and various oligomeric glycols: oligoesterdiol \u2013 oligo(diethylenglycol adipat) 800, oligoethertriol oligo(oxypropylenglycol) and oligoetherdiol oligo(oxyprolylenglycol) 1000. According to analysis of EPR spectra of nitroxyl radical TEMPO it was found that the dynamic characteristics of dye doped and initial polyurethanes, as well as the dyes effect on the polymer loosening, is determined by the nature, length and functionality of glycol component. The data obtained can be used to formulate the composition of active medium based on dyed polyurethane with desired dynamic properties of the matrix.<\/em><\/p>\n
