Abstract
The H-2 NMR spectra of main-chain deuterated polystyrene in a polystyr ene/poly(vinyl methyl ether) (PS/PVME) blend are observed at various t emperatures. The spectra are simulated by assuming microbrownian motio n and vibrational motion. The temperature and the composition dependen ces are discussed. A distribution of mobility in space is suggested. T he distribution is caused by spatial microheterogeneity in the blend.
