METHOD FOR SYNTHESIS OF HYDROGELS BASED ON POLYHEXAMETHYLENEGUANIDINE HYDROCHLORIDE Russian patent published in 2018 - IPC C08J3/75 C08G73/00 A61L2/16 

Abstract RU 2645551 C2

FIELD: chemistry.

SUBSTANCE: method for production of a polyhexamethyleneguanidine hydrochloride gel is implemented using aldehydes as the cross-linking agent of the polymer end groups at mixing of an aqueous solution of polyhexamethyleneguanidine hydrochloride at a concentration of 25 wt % with an amount of formaldehyde equivalent to the amount of the amino end groups of polyhexamethyleneguanidine hydrochloride at a room temperature followed by washing with distilled water for aldehyde residues removal.

EFFECT: simplification and acceleration of polyhexamethyleneguanidine hydrochloride gelling process with increased yield of hydrogel.
