Amorphous poly(thioarylene)s containing a methyl substituent and/or an ether bond in the main chain were prepared via oxidative polymerization of diaryl disulfides using 2,3‐dichloro‐5,6‐dicyanobenzoquinone. The resulting poly(thio‐2,6‐dimethyl‐1,4‐phenyleneoxy‐1,4‐phenylene) having alternating ether and thioether bonds shows a better solvent solubility and has a higher glass transition temperature ( T g ) (182°C) than non‐substituted poly(thio‐1,4‐phenylene). Polymerization of methyl substituted diphenyl ether derivatives with disulfur dichloride has been also developed for a one‐pot synthesis of amorphous poly(thioarylene)s.
