説明
Intensities of small-angle X-ray scattering of a poly(tetraoxane) system, on both the direction of the equator and that of the meridian, increase by reducing the amount of unreacted tetraoxane, indicating the formation of voids.<BR>A broad scattering maximum in the meridian besides a spot-like scattering corresponding to 100-Å spacing was observed in a polymer prepared at 105°C. The broad maximum shifts to a low angle by annealing the sample below 140°C, i.e., at a temperature range which has no influence on the polymer chain aggregation. The shift is associated with the sublimation of the unreacted monomer or the thermal decomposition of low-molecular-weight polymer. These materials are held in voids formed periodically on the fibrillar polymer crystal.<BR>The fibrillar structure of poly(tetraoxane) seems to be an extended polymer chain aggregation with a periodic void appearance, i.e., a stacking of crystallites along the c-axis, while a lamellar crystal corresponding to 100-Å spacing situates between these fibrils.
