Heat treated poly(p-phenylene benzobisthiazole) (PBZT) fibers tested in tension result in two types of failure modes. In failure mode I, the fiber exhibits a relatively sharp break; mode I1 is characterized by significant axial fiber splitting. Approximately 20% of the fibers failed in mode I1 when

## Abstract Fibers spun from anisotropic solutions of a lyotropic rigidβrod polymer, poly(paraβphenylene benzobisthiazole) [PBZT], were coagulated into homogeneous nonsolvents including a solution of 18% iodine/82% ethanol, ethanol, and water. The effect of these coagulants on the structure and mec
Chain coherence length of rigid-rod poly(p-phenylene benzobisthiazole) (PBZT) and its derivatives in the solid state was determined from the wide-angle X-ray diffraction patterns of axially disordered crystal. The degree of the PBZT main chain extension was estimated from the coherence lengths and w
The high temperature properties of Poly( p-phenylene-2,6-benzobisoxazole) (PBO) fiber are examined and compared with those of the p-Aramid fiber. In particular, the temperature dependence of tensile strength of the PBO fiber is reported for the first time. The PBO fiber has 100ΠC higher decompositio
The blending of a precursor polymer for poly(p-phenylene benzobisthiazole) (PBZT) with various matrix polymers was attempted, followed by heat conversion of the PBZT precursor polymer to obtain molecular composites consisting of PBZT and the matrix polymers. A higher concentration of mixed solution
