    摘要： A polybenzazoleolybenzazole having a residual content of a BB-PBZ monomer of not more than 0.010 wt%, which is obtained by dehydration polymerization condensation of an AA-PBZ monomer of the formula (I) wherein Ar is a quadrivalent aromatic organic residue and X is O, S or NH, and a BB-PBZ monomer of the formula (II)

            W―Z―W     (II)

    wherein Z is an optionally substituted divalent aromatic organic residue and W is a carboxyl group or a group derived from the carboxyl group, which is reactive with -XH in the AA-PBZ monomer. Because the residual content of the BB-PBZ monomer in polybenzazole is not more than 0.010 wt%, a polybenzazole fiber having a small filament denier can be produced stably at a high speed without suffering from thread breakage during the production.
