Polycondensation in polyphosphoric acid of 2,5-diamino-1,4-benzene dithiol dihydrochloride with bicyclo[2.2.2]octane-1,4-dicarboxylic acid, as well as the corresponding dimethyl ester or diacid chloride, led to rigid-rod benzobisthiazole polymers. Co

Graft copolymers of rigid-rod polymers, specially synthesized for single-component molecular composites, were investigated by wide-angle X-ray scattering. The copolymers consist of a flexible poly(ether ketone) (PEK) side chain attached to a rigid-ro

End-capped poly(p-phenylenebenzobisthiazole) structures containing randomly distributed 2,6-dimethylphenoxy pendants along the rigid-rod backbone were synthesized through the copolycondensation of 2,5-diamino-1,4-benzenedithiol dihydrochloride with t
