Notes:
Poly(vinyl chloride) was post-polymerization copolymerized with a highly basic amine, piperazine, using an aprotic solvent, dimethyl sulfoxide. By using this highly dipolar solvent, a more dilute nucleophile concentration and a lower reaction temperature were possible than in methanol-moderated reactions. The linear substitutional reaction dominated over both the crosslinked substitutional reaction and the elimination reaction. From the nitrogen assays, pH response curves, and colorimetric results, the evidence suggests that this route may be more promising for fabricating electrode membranes or other components in which an ionically conductive film is desirable.
