Abstract Poly(acryloxyethyl‐trimethylammonium chloride‐ co ‐2‐hydroxyethyl methacrylate) [poly(Q‐ co ‐H)] was prepared by free radical polymerization in aqueous solution at 60°C using potassium persulfate as initiator. Spectroscopic characterization confirmed the formation of poly(Q‐ co ‐H) and the molar fractions of acryloxyethyl‐trimethylammonium chloride monomer units incorporated in the copolymers were determined by potenciometric titrations. The monomer reactivity ratios for Q and H are found to be r Q = 0.04 ± 0.01 and r H = 3.22 ± 0.84 using Fineman–Röss method and r Q = 0.06 and r H = 3.61 using Genetic Algorithms method. Finally we studied reaction between poly(Q‐ co ‐H) and sodium alginate by conductimetric measurement. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
