METHOD FOR PREPARING POLYGUANIDINE STRUCTURING AGENT AND STRUCTURING AGENT FOR POLYGUANIDINE Russian patent published in 2004 - IPC

FIELD: organic chemistry, polymers, chemical technology.

SUBSTANCE: invention relates to a method for preparing structuring agent for polyguanidine and to structuring agent for polyguanidine that can be used in chemistry of polymers and as disinfectant for disinfecting different objects and subjects. Method for preparing structuring agent for polyguanidine involves interaction of different derivatives of polyguanidine with epichlorohydrin in the equimolar ratio at temperature 40-60⁰C in mass or an aqueous solution. Structuring agent for polyguanidine is represented by the following structural formulas:

wherein A is Cl^-, HCOO^-; R is hydrogen atom (H), Alk, AlkAr; x = 4, 6, 12; n = 4-30; or

wherein A is Cl^-, HCOO^-; R is hydrogen atom (H), Alk, AlkAr; x = 4, 6, 12; n = 4-30; or

wherein A is Cl^-, HCOO^-; n = 15-30; or

wherein A is Cl^-, HCOO^-; n = 15-30; or

wherein A is Cl^-, HCOO^-; R is hydrogen atom (H), Alk, AlkAr; n = 4-30; or

wherein A is Cl^-, HCOO^-; R is hydrogen atom (H), Alk, AlkAr; x = 4, 6, 12; n = 4-30; or

wherein A is Cl^-, HCOO^-; n = 15-30; or

wherein A is Cl^-, HCOO^-; n = 15-30. Invention provides the development method for preparing safe and stable polymeric structuring agent that is able structure polyguanidine effectively with formation of three-dimensional polymeric structure constructed by covalent linkages.

EFFECT: improved preparing method.
