Abstract

The precipitation of kraft lignins with cationic polymers was investigated. Eighty to ninety percent of the lignin could be precipitated with polyamines or poly(diallyldimethylammonium chloride). The yield of precipitate was not sensitive to the molecular weight of the cationic polymer, the concentration of sodium chloride or the detailed chemical structure of highly charged cationic polymers.
