Abstract
The structure of the polypropylene compositions obtained as a result of modification by multicomponent systems has been studied by the method of pulsed NMR spectroscopy. The times of relaxation were analyzed in a wide temperature range. The character of the occurring changes at the level of supermolecular structure is described. It is shown that the amplifications manifesting themselves upon modification of polypropylene by mixtures based on 2,4-toluene diisocyanate (TDI) and e-caprolactam (e-CL) are associated with the change in the character of intermolecular interaction and with the formation of a more ordered structure of the polymer.
