Abstract
Wide-line NMR studies of poly(tetrahydrofuran) (PTHF) have been made on drawn and rolled sheets in the range of temperature from −196 to 37°C. The NMR spectra showed pronounced anisotropy with variation of the arrangement of the PTHF sheet in the applied magnetic field. The second moments of the NMR spectra for drawn and rolled sheets were well explained by the uniaxial and double orientations of the crystallites in the sheet. In the rolled sheet, the (100) plane of crystal, to which the zig-zag plane of the molecule is parallel, was found to be oriented preferentially parallel to the sheet plane. A reduction in the second moments of the crystalline regions with increasing temperature was interpreted in terms of the molecular motion in the crystal. A theoretical calculation showed that such a motion involves a rotational oscillation around the molecular axis.
