Poly(oxoviny1 su1fide)s 3 were prepared by vinylogous nucleophilic substitution polymerization of bis(3-chloroacryloyl) derivatives of benzenes ( l a and l b ) with 4,4'-oxydibenzenethiol (2). The synthesis involves solution polycondensation and two-phase polycondensation with phase transfer catalysts. Polymers having inherent viscosities in the range of 0,2-0,7 dl * g-' were obtained quantitatively by both methods. They are soluble in concentrated sulfuric acid, dichloroacetic acid, and rn-cresol, and practically insoluble in polar aprotic solvents and common organic solvents. Thermogravimetric studies in both air and nitrogen atmospheres indicated that the decomposition temperatures for 10% weight loss of the polymers were about 400°C.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
