Mobility of amorphous polymers such as poly(vinyl chloride) (PVC), atactic polypropylene (PPA) and ethylene-propylene-diene terpolymer (EPDM) were studied by proton spin-lattice relaxation time (T-1 H), proton spin-lattice relaxation time in the rotating frame (T-1(H) rho), and dipolar dephasing pulse sequence. The data are discussed in terms of mobility and by the distribution of configurational sequences.
