Poly(diallyldimethylammonium chloride) (polyDADMAC)
CAS Number: 26062-79-3
PolyDADMAC is a linear, fully water-soluble cationic polymer widely used as a primary coagulant and charge-neutralization agent in drinking water, wastewater, and paper manufacturing. It provides excellent removal of humic substances, turbidity, and negatively charged contaminants. PolyDADMAC is commonly used in combination with inorganic coagulants to reduce metal salt dosage and improve sludge management.
