CHEMICAL-REACTIONS ON REDOX POLYMER PRECURSORS .2. AMINOMETHYLATION AND SULFONATION

Five redox polymer precursors, poly(5-vinyl-1,3-benzodioxole) (poly I) , poly(3,4-dimethoxystyrene) (poly II), poly(2,3-dimethoxystyrene) (po ly III), poly(6-vinyl-1,4-benzodioxane) (poly IV) and poly(4-vinyl-1,3 -benzodioxole) (poly V), underwent aminomethylation and sulfonation re actions. Phthalimidomethylation was realized via the Gabriel reaction, which upon hydrazinolysis yielded aminomethylated resins, valuable in termediates for subsequent modification. The sulfonation of these poly mers with chlorosulfonic acid followed by treatment with tetramethylam monium chloride afforded new polyelectrolytes. (C) 1997 Elsevier Scien ce Ltd.
