Time-resolved structural studies in fiber processing

Time‐resolved and off‐line synchrotron wide‐angle and small‐angle x‐ray scattering (WAXS and SAXS) was used to study the structure formation in poly‐p‐phenylenebenzobisoxazole (PBO) fibers during various stages of spinning, coagulation, and heating processes. WAXS data could be explained in terms of...

Zusammenfassung:Time‐resolved and off‐line synchrotron wide‐angle and small‐angle x‐ray scattering (WAXS and SAXS) was used to study the structure formation in poly‐p‐phenylenebenzobisoxazole (PBO) fibers during various stages of spinning, coagulation, and heating processes. WAXS data could be explained in terms of liquid‐crystalline structures of varying degrees of order. A structure model is proposed that is in accordance with the observed SAXS four‐point pattern.
