Abstract:

Thermotropic polysulfonyl hydroquinone terephthalate with either H or CH3 in the lateral substituent, was aligned by drawing from nematic melts. Virtually identical xray intensity distributions were recorded consisting of disks of intensity periodically spaced along the meridian and concentric rings of intensity lying in the equatorial plane of reciprocal space. They correspond to what is expected for the hexagonal packing of parallel periodic chains that are randomly displaced along the chain axes. Using interactive graphics, appropriate molecular models were deduced in conformity with the observed diffraction intensities. X Ray diffraction, Terephthalates, Liquid crystalline polymers.
