Poly(p-phenylene benzobisthiazole) (PBZT) polymer film, prepared by a doctor-blading technique, was studied by wide-angle X-ray scattering. Emphasis was placed on the anisotropic arrangement of the extended rigid-rod chains against the macroscopic axes. Two X-ray patterns, one measured with the X-ray beam perpendicular to the plane of the film surface and the other with the beam parallel to the surface plane, revealed a unique morphological feature: the large molecular plane of the PBZT chain is lying perpendicular to the film surface plane with the long polymer axis being random but lying in the plane of the film surface.
