Anionic polyacrylamide (APAM)

Anionic polyacrylamide (APAM) appears as white powder with a molecular weight ranging from 3 million to 25 million. It has good water decomposition properties and can be dissolved in water and insoluble in organic solvents. The effective pH value range is 6 to 10. It has the characteristics of a high polymer electrolyte in a neutral alkaline medium, is sensitive to salt electrolytes, and can cross-link with high-valent metal ions to form an insoluble gel.
