The cationic monomers, MPDMAC(16) and MPDMAC(18) were obtained by quaternization of methacrylamidopropyl-N,N'-dimethylamine with n-alkyl iodides (1-iodohexadecane and 1-iodooctadecane) in ethyl acetate. Hydrophobic ionomers of MPDMAC16 and MPDMAC(18) with N-substituted acrylamides were prepared at 60 +/- 0.1 degrees C in DMF using AIBN initiator. The cationic monomers and ionomers were characterized by H-1- and C-13-NMR spectroscopy. The copolymer composition was evaluated from elemental analysis data using carbon/nitrogen (C/N) ratio. The molecular weight distributions of ionomers were obtained from GPC analysis. Both the dilute solution and concentrated solution properties of ionomers were studied by viscometry at 30 degrees C.
