Miscibility and molecular motion of a poly(methyl acrylate)/poly(vinyl acetate) blend are studied by high-resolution solid-state C-13 NMR techniques. Observed H-1 relaxation times indicate that they are miscible on the scale of 20-30 Angstrom. The temperature dependence of the C-13 linewidth is examined to investigate effects of blending on molecular motion of each component polymer. Two models for the temperature dependence of the correlation time of motion are examined. One is an Arrhenius dependence and the other is a WLF dependence. Both models explain the observed temperature dependence adequately. It is shown that by blending molecular motions of PMA and PVAc becomes similar.
