It was established that the reaction of sodium thiosulfate with poly(p-phenylenediamine)—poly(1,4-benzoquinonediimine-N,N′-diyl-1,4-phenylene) and its derivative with acetylated end amino groups results in 1,4-addition of thiosulfate to quinonediimine groups. The same reaction was investigated with its model compound N,N′-di(4-acetaminophenyl)-1,4-benzoquinonediimine. The reaction conditions for high...
Poly(1,4-benzoquinonediimine-N,N-diyl-1,4-phenylene) having similar structure to pernigraniline was synthesized by chemical oxidative polymerization of p-phenylenediamine and its salt using potassium peroxydisulfate as an oxidant in molar ratio 1:0.8, in acetic acid, at 278 K. Acetylation of amino end groups of polymers were carried out aiming to prevent self-condensation of amino groups with 1,4-benzoquinone...
