Esters of N-hydroxypyridine-2-thione (Barton esters, BE) were appended to a carboxylated poly(arylene ether sulfone), PSF-COOH, backbone. Irradiation of the polymer bound Barton ester in monomer/DMF solution initiated a free radical graft polymerization at 25°C without promoting concomitant homopolymerization. The following monomers were grafted to PSF backbones using this technique: styrene, methyl...
Chloromethylation and lithiation were amongst the different chemical reactions carried out on five redox polymers: poly(5-vinyl-1,3-benzodioxole), poly I; poly(3,4-dimethoxystyrene), poly II; poly(2,3-dimethoxystyrene), poly III; poly(6-vinyl-1,4-benzodioxane), poly IV; poly(4-vinyl-1,3-benzodioxole), poly V. In the course of the former reaction, an inter- and/or intrapolymeric Friedel-Crafts alkylation...
Five redox polymer precursors, poly(5-vinyl-1,3-benzodioxole) (poly I), poly(3,4-dimethoxystyrene) (poly II), poly(2,3-dimethoxystyrene) (poly III), poly(6-vinyl-1,4-benzodioxane) (poly IV) and poly(4-vinyl-1,3-benzodioxole) (poly V), underwent aminomethylation and sulfonation reactions. Phthalimidomethylation was realized via the Gabriel reaction, which upon hydrazinolysis yielded aminomethylated...
