FIELD: metallurgy.
SUBSTANCE: procedure consists in dissolving poly-hexa-methylene-guanidine of hydrochloride in water solution of ammonia. Phenols and formalin by parts are poured to produced solution. Further solution is heated at boiling temperature during 1-5 h. Produced in total volume emulsion is poured out into water alkali solution. Also settled resin is washed from alkali and dried.
EFFECT: production of poly-hexa-methylene-guanidine insoluble in water.
