Abstract New copolymer of 2,2-diallyl-1,1,3,3-tetraethylguanidiniumchloride and 2-hydroxyethylacrylate was obtained by free radical copolymerization technique for the first time. It was found that 2,2-diallyl-1,1,3,3-tetraethylguanidinium chloride is involved in copolymerization with acrylate to give rise to pyrrolidinium structures. Chemical modification of guanidine-containing polymer was carried out in two directions. According to one direction, polymeric guanidine-containing conjugates were obtained by anion exchange reaction via hydroxide. On the other hand, new biocide polymeric guanidinium salts were obtained by the interaction of acrylate hydroxy group of the copolymer with biologically active acids in the presence of dehydrating agent dicyclohexylcarbodiimide and esterification catalyst 4-dimethylaminopyridine. NMR, FTIR and element analysis were used to confirm the chemical structure and element composition. New guanidinium polyelectrolytes are effective in controlling Gram positive and Gram negative bacteria.
