Abstract The radical copolymerization of N ‐phenylmaleimide was carried out with β‐methyl hydrogen itaconate at 70°C for 12 h. The copolymers were characterized by elemental analysis, thermal analysis, Fourier transform infrared, and 1 H‐NMR spectroscopy. The monomer reactivity ratios were determined by the Kelen–Tüdös and Fineman–Ross methods. These values demonstrated that the copolymerization reaction produced statistical copolymers with a tendency to alternation. The retention capacity of the copolymers for Cu 2+ ions varied from 296 to 348 mg/g at pHs 5 and 7. © 2005 Wiley Periodicals, Inc. J Appl Polym Sci 95: 1361–1367, 2005
