2H solid-state NMR wasused to probe the dynamics of the plasticizer di(propylene glycol) dibenzoate(DPGDB-d10) in mixtures with poly(vinyl acetate) (PVAc). 2H NMRspectra were obtained from PVAc samples with different deuterated plasticizercontents at various temperatures. The experimental 2H NMR lineshapes were fitted using a set of simulated spectra obtained from the MXQETprogram. The simulation was based on the superposition of a two-site jumpmotion, 180� ring flips, and the isotropic motions.
