“…The polymerization was proposed to proceed by the reaction of the amine and sulfur monochloride (S 2 Cl 2 ) followed by electrophilic aromatic substitution to yield the C–S bond in the product. Similarly, the polymerization of aniline with S 2 Cl 2 was reported in 1974 by different authors to proceed by similar mechanisms to yield polymers with the NSS functional group . This polymer was thermally stable and was found to be paramagnetic.…”

Polymerizations of phenylamines with a disulfide transfer reagent to yield poly [N,N-(phenylamino) disulfides] (poly-NADs) were investigated due to their unique repeat units that resulted in conjugation along the backbone that was perturbed by the aromatic rings and gave different colors for the polymers. These polymers were synthesized from 10 different anilines and sulfur monochloride in a step-growth polymerization. The polymers were characterized by nuclear magnetic resonance spectroscopy, size exclusion chromatography-multiangle light scattering, and UV−vis spectroscopy. These polymers possessed a polymeric backbone solely consisting of nitrogen and sulfur [−N(R)SS−], which was conjugated and yielded polymers of moderate molecular weight. Most notably, these polymers were an array of colors ranging from pale yellow to a deep purple depending on the substitution of the aromatic ring. The more electron-poor systems produced lighter yellow polymers, while the electron-rich systems gave orange, green, red, and even purple polymers.
