The study of isotactic polypropylene and ethylene-propylene-diene terpolymer and of the polymer blend composed of these components was made with the use of the broad line ¹H nuclear magnetic resonance technique. Conclusions concerning the relaxation processes in the particular phases of the PP and blend were drawn from the temperature dependences of the mass fractions of the structural phases. The lower crystallinity and the higher fraction of intermediate regions of the blend, compared with those of neat i-PP, were found.
