Copolymers of N ‐vinylcarbazole (NVC) and the quarternary salt of N,N ‐dimethylaminoethyl methacrylate with ethyl iodide (DMAEMA·EI) were prepared by free‐radical copolymerization in dimethyl sulfoxide at 70°C using α,α′‐azobisisobutyronitrile (AIBN) as an initiator. The reactivity ratios of both monomers were determined according to the general copolymerization equation using the extended Kelen–Tüdös method and found to be r 1 = 0.12 (±0.04) and r 2 = 0.84 (±0.08). Copolymers were characterized by viscosity measurements and thermogravimetric analysis (TGA). Copolymers containing DMAEMA·EI higher than 60 mol % were water‐soluble. © 1998 John Wiley & Sons, Inc.
