PolyDADMAC, poly(diallyldimethylammonium chloride), is a high-charge-density cationic polymer supplied as a clear to amber viscous aqueous solution (20-50% solids), exhibiting strong electrostatic interactions for coagulation and demulsification. It polymerizes via free radical initiation, offering molecular weights from 100,000 to 500,000 Da for optimized performance in water-based systems per ChemSpider structural data.

PolyDADMAC
Applications
Critical in municipal wastewater clarification; in papermaking for retention and drainage aids; in oilfield operations for clay stabilization; in textile wastewater decolorization; and in mining slurries for solid-liquid separation in resource extraction processes.
Safety & Risks
Eye and skin irritant with potential for sensitization upon repeated exposure; aquatic toxicity mandates controlled discharge. Low volatility but avoid aerosol formation; implement spill containment and use nitrile gloves.
Packaging
Delivered in 1000 kg totes with polyethylene liners and quick-connect fittings. Upright storage in shaded, bunded areas to prevent environmental release from container breaches.
