A process for preparing a methanolic solution of poly(allylamine) is disclosed, wherein an inorganic acid salt of polyallylamine (e.g. hydrochloride, phosphate or sulfate) is ground into a fine powder, which powder is dispersed in a methanolic solution of caustic alkali (e.g. NaOH or KOH) or ammonia and treated at the temperature of 0 DEG to 65 DEG C. for a period of 10 hours or less. |
