Abstract: Qualitative and quantitative composition of complex formed during chromium(III) acetate reaction with terpolymer of acrylamide, 2-acrylamide-2-methyl-propanesulfonic acid sodium salt and sodium acrylate in an aqueous solution resulting in transformation of linear macromolecules into a space network has been estimated by NMR 13C spectroscopy. A cross-linking has been shown to proceed only by an interaction of chromium(III) cation and carboxylate groups of the copolymer. Amide and sulfogroups of terpolymer don’t form complex compounds in spite of fact that their quantity is larger comparing to carboxylate groups. The complex formed has been revealed to be consisted of three bidentate carboxylate groups Cr(III) : COO– ratio being less or equal to 1:3. The equilibrium between monodentate and bidentate form of carboxylate ligands in the complex compound in an aqueous solution has been discussed.
