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.
