X-Ray Diffraction Studies of the Structure of Ordered Polymers and Related Electro-Active Materials
Abstract
The structures of poly (p-phenylenebenzobisthiazole) (PBZT) and poly(p-phenylenebenzobisoxazole) (PBO) fibers have been determined by fiber diffraction techniques (see Reprint 4 for details). D-spacings were obtained from equatorial and meridional scans recorded on a four-circle diffractometer. Intensity data were derived from x-ray rotation patterns taken on Weissenberg and vacuum cylindrical cameras. Unit cells were found to be monoclinic and non- primitive, each containing two chains per cell. The conformational torsion angle between the bisthazole and phenylene units and the orientation of chains within the unit cells were obtained from a 'linked-atom least-squares' (LALS) refinement procedure.
