Popis: | Polystyrene containing deuterium in 10-20% of the center of the chain is examined between 380 and 470 K. The results suggest that deuterium NMR spectroscopy may not be as useful for the study of very slow reorientation in polymer melts as are forms of NMR spectroscopy that have a longer effective time scale as 13 C and 1 H NMR |
