COPOLYMERS OF POLYGUANIDINE SALTS Russian patent published in 2003 - IPC

FIELD: organic chemistry, polymers. SUBSTANCE: invention relates to preparing copolymers of polyguanidine salts that can be used in medicine, veterinary science as disinfecting agent. Invention proposes copolymer of polyguanidine salt of the general formula (I) wherein R₁ is hydrogen atom, higher alkyl, aralkyl, alkylenesilane, alkoxysilane; R₂ is alkylene, arylene (Ar), oxyalkylene of the formula: [-CH₂]_pO[-CH₂-]_qO[-CH₂-]_r, aminoalkylene of the formula: [-CH₂-]_sNH[-CH₂-]_t, wherein x : (n-x) = (9:1)-(1:9); n = 10-60; Ar means ortho-, meta- and para-isomers of C₆H₄; indices p, q, r, s, t = 2-4; Gl means gluconate of the formula: C₆H₁₂O₇; A is anion of organic physiologically active acid taken among group including alkyl- and arylcarboxylic acids, oxyacids or heterocyclic compounds with acidic properties. Invention provides the development of highly effective complex agent with low toxicity. Copolymers of salts show good solubility in water and have no odor. EFFECT: valuable medicinal properties of copolymers. 3 tbl
