METHOD OF BIOCIDE POLYGUANIDINE PRODUCTION AND BIOCIDE POLYGUANIDINE Russian patent published in 2008 - IPC A61K31/155 A01N33/02 C08L75/02 C08G73/00 A61L2/16 C07C279/02 A61P31/00 

FIELD: chemistry.

SUBSTANCE: method includes polycondensation of α,ω-diamine with guanidine salt. Hydrophobic α,ω-diamine mixed with hexamethylene diamine or mixed with 4,9-dioxadodecadiamine H₂N-(CH₂)3-0-(CH₂)4-0-(CH₂)3-NH₂ is used in the following ratio, % w/w: hydrophobic α,ω-diamine - 16-60, hexamethylene diamine or 4,9-dioxadodecadiamine - 84-40, and as a hydrophobic α,ω-diamine 1,10-decamethylene diamine H₂N-(CH₂)₁₀-NH₂ or 1,12-dodecamethylene diamine (H₂N-(CH₂)₁₂-NH₂ or N,N-bis-(3-aminopropyl) dodecylamine are used, biocide polyguanidine is obtained by the indicated method. It is characterized by hydrophilic and hydrophobic properties and is represented by the following formula: where n = 30-50, , R₁ and R₂ = H, CH₃, C₂H₅, C₄H₉, C₈H₁₇, CH₂C₆H₅.

EFFECT: invention allows to obtain water soluble products.
