Novel copolymers showing interactions of amidinium-carboxylate groups in water

Original Paper


Four hydrophobic amidine containing monomers N-(pyridin-2-yl)methacrylamide (3), 5-(pyridin-2-ylamino)pentyl methacrylate (7), S-5-(isopropenylcarbonyloxy)pentyl-N,N-diphenylthiourea (9) and methyl-5-guanidino-2-methacrylamidopentanoate (12) were synthesized and copolymerized with a water soluble co-monomer N,N-dimethylacrylamide (13) or N-isopropylacrylamide (22). The second component was a copolymer containing methacrylic acid (19) and 13/22. By combination of these two components the formation of amidinium-carboxylate interactions was determined by dynamic light scattering (DLS), 1H-NMR spectroscopy and rheology measurements.
