Hydrogen spin-lattice relaxation times were determined directly by the traditional inversion recovery pulse sequence (180[degrees] - [tau] - 90[degrees]); the instrument software calibrated the 90[degrees] pulse of 4.
The low field NMR measurements, that is, the measured hydrogen spin-lattice relaxation times, showed that PMMA and PVDF form partially miscible blends.
These distribution fittings corroborate the interpretation of spin-lattice relaxation times.
The low-field NMR measurements through the hydrogen spin-lattice relaxation time showed that the addition of different contents of PMMA into PVDF produces blends with partial miscibility.

As shown by Schantz (2), carbon spin-lattice relaxations for PMMA at room temperature are not sensitive to changes in segmental motion in blends with PEO.
