Processable precursor polymers to poly(phenylene bisbenzoxazole)s (PBOs) have been prepared and studied. The precursor polymers were synthesized by the polycondensation of 1,4-bicyclo[2.2.2]octyl-2,5diethanoate dicarboxylic acid or 1,4-bicyclo[2.2.2]octyl-2,5-diol dicarboxylic acid with 3,3'-dihydro
