  Rigid-rod copolymer compositions incorporating PBO (poly(p-phenylenebenzobisoxazole)), DiOH-PBO (poly(2,5-dihydroxy-1,4-phenylenebenzobisoxazole), DiOH-PBI (poly(2,5-dihydroxy-1,4-phenylenebenzobisimidazole)), DiOH-PyBI (poly(2,5-dihydroxy-1,4-phenylenepyridobisimidazole), PBZT (poly(p-phenylenebenzobisthiazole)) and its corresponding dihydroxy analogues attached to a flexibilizing hexafluoroisopropylidene linkage are described. Also described are their fabrication into fibers by a dry jet wet spinning technique and the measured fiber mechanical properties. The copolymer compositions are highly flame-resistant and have potential utility for fire-protective clothing.
