Abstract
Studied were made of the temperature dependences of line width, second moment and the form of PMR line in the temperature range of −190+60° using isoprene rubber, crude and vulcanized systems (unfilled and containing carbon black, an active technical carbon). It was shown that vulcanization displaces transition from the glassy state to the high elastic state by 10° in the direction of higher temperatures. Crude carbon produces oriented ranges, in which macromolecular mobility is higher than in inhibited regions of unfilled vulcanizates. A narrow component is observed in spectra of samples containing untreated carbon, which is due to groups containing proton on the surface of untreated carbon particles.
