実験手順
Guanidine hydrochloride (200 parts) and hexamethylene diamine (292 parts) were heated to 120° C. for 4 hours under a nitrogen atmosphere. The temperature of the reaction mixture was then raised to 150–170° C. for a further 10 hours. The product was cooled to 80° C. and 1,5-pentanediol (400 parts) was added while the temperature was maintained at 80° C. until dissolution occurred. The mixture was then cooled to give a solution of polyhexamethyleneguanidine (prepolymer 3) in 1,5-pentanediol.
