Abstract: Low molecular weight Poly(p-phenylenebenzobisthiazole) (PBZT) was crystallized in sulfuric acid above and below cloud point temperature respectively, and multi-layer lamellar crystal and fascicular crystal composed of rod-like crystals were obtained. Through transmission electron microscope (TEM) observation and selected area electron diffraction (SAED) study, it was found that, for fascicular crystal, the molecular chains were perpendicular to the direction of long axis of rod-like crystal, and the average width of rod-like crystals was close to the average length of molecular chains. While for lamellar crystal, the molecular chains were perpendicular to the surface of lamellar crystal in the main.
