Abstract |
|
内容記述 |
H-2 NMR measurements were carried out for a series of poly(alkyl L-glutamate)s (PALG) in which the H-1 of the amide group in the main chain is replaced by H-2 in order to investigate the mobility and motional mode of the main chain. At low temperature, the H-2 spectra were typical powder patterns, which have three principal values. The temperature dependencies for the H-2 NMR spectra varied with the side chain length. For PALG with a short side chain length, Deltanu(1), Deltanu(2), and Deltanu(3) are almost constant in all temperature ranges. As the side chain length increases, the difference between the peaks and shoulders decreased with temperature. For PG-12-N-D, the peaks and shoulders are fused at high temperature in a liquid crystalline state. The mobility and molecular motion of the main chain is discussed based on the obtained H-2 NMR spectra. |
