Three kinds of copolymers of pendant ethyl viologen methacrylate with acrylamide, methyl methacrylate and styrene were synthesized. From the results of cyclic voltammograms and ultraviolet-visible spectra it was concluded that the nature and the content of comonomer have significant influences on the electrochemical activities and stability of copolymers, but not on affect the color of reduction states of these copolymers. The color of these copolymers changes reversibly form yellow brown to palle violet, and to blue violet.
