In this work we have investigated how the dynamics of poly(vinyl methyl ether), PVME, changes by blending with deuterated polystyrene. The experimental techniques used were dielectric spectroscopy, quasielastic neutron scattering, and 13C nuclear magnetic resonance. By means of these techniques, the dynamics of the poly(vinyl methyl ether) units in the blends can be selectively investigated in a huge time range (101−10-11 s). Two different blend compositions have been investigated. The main relaxation processes observed in this range are the secondary β-process and the segmental α-relaxation. It turns out that the β-relaxation is not affected by blending. The data analysis procedure followed by us in the case of the α-process is based on the assumption that the dynamics of the PVME segments in the blends is a superposition of dynamical processes with the same shape as that in pure PVME, but with the relaxation times distributed due to the presence of concentration fluctuations. From this analysis we found that, in the blends, and in pure PVME as well, the results obtained by means of the different techniques can consistently be described with the same set of parameters. Moreover, the temperature dependence of the distribution of relaxation times in each blend composition can be accounted for by a single, temperature-independent, Gaussian distribution of the Vogel−Fulcher temperature, T0, the average and the variance of the distribution increasing as the PVME concentration decreases. Our results suggest that a significant number of PVME segments in the blends move faster than in pure PVME. Furthermore, our results strongly indicate that each polymer component of the blend exhibits very different α-relaxation rates, i.e., different “glass transitions”. Several implications of these results concerning the usually accepted ideas of polymer blend dynamics are outlined.
