Different types of sulfobetaines and their corresponding cationic monomers and polymers derived from N,N ‐dialkylamino phenyl methacrylamide have been synthesized for this study. Comparing the chemical shifts in 1 H and 13 C NMR of the methylene groups in the cationic monomers and betaines reveal that the respective methylene groups are clearly distinguishable from each other. Results obtained from the intrinsic viscosity for zwitterionic poly(DEMAPhAPS) are opposite to that for the corresponding cationic poly(DEMMAPhAMS).
