Abstract 2,2,6,6‐Tetramethylpiperidine‐N‐oxyl (TEMPO)‐mediated free radical polymerization of 4‐vinylpyridine is found to proceed in a “controlled” manner. A linear increase of molecular weight along with an increase in conversion occurs at varying temperatures. Polymerization of styrene with a poly(4‐vinylpyridine) block as macromer results in block copolymers with narrow polydispersity. The polymers are characterized by different size exclusion chromatography methods and converted to cationic polyelectrolytes as well as to polysulfo‐ and polycarbobetaines.
