Notes:
The radical copolymerizations of commercially available cationic monomers (M1) with acrylamide (M2) have been investigated at pH 6.1 in aqueous solutions. The cationic groups in copolymers were analyzed by a colloid titration method and the reactivity ratios were determined by the Fineman-Ross method. The values of r1 and r2 were 1.71 and 0.25 for methacryloyloxyethyltrimethylammonium chloride—M2, 1.68 and 1.26 for N,N-dimethylaminoethylmethacrylate—M2, 1.13 and 0.57 for methacrylamidopropyltrimethylammonium chloride—M2, 1.10 and 0.47 for N,N-dimethylaminopropylmethacrylate—M2, 0.47 and 0.95 for N,N-dimethylaminopropylacrylamide—M2, 0.48 and 0.64 for acryloyloxyethyltrimethylammonium chloride-M2, and 0.58 and 6.7 for dimethyldiallylammonium chloride-M2 systems. The Alfrey-Price Q and e values were calculated and the linear relationship between log Q and ultraviolet absorption maxima of cationic monomers was found.
