Abstract:
Very slow mol. motions were detected in cryst. polyoxymethylene at 25 and 50 Deg by 2D-exchange NMR in a slowly rotating sample. These motions are assocd. with the a-relaxation obsd. in mech. and dielec. loss measurements. The assocn. of this relaxation with a cryst. mechanism was confirmed.
