摘要：

Samples of PVC plasticized by di-isobutylphthaiate and di-2-ethylhexylphthalate, with plasticizer content varying up to 180 parts per hundred, have been examined using solid-state H-1- and C-13-NMR. Proton spin-lattice relaxation times in both the laboratory and the rotating frames were measured, with analysis into multi-exponential components where necessary. Crosspolarisation magic-angle spinning C-13 spectra have also been obtained, including variation with contact time. The data are discussed in terms of the domain structure of the samples at the microscopic level and of the role of the plasticizer.
