Polydiallydimethylammonium chloride (shortened PolyDADMAC or PolyDDA) is a homopolymer of diallydimethylammonium choride (DADMAC). The molecular weight of polyDADMAC is typically in the range of hundreds of thousands of grams per mole, and event up to a million for some products. polyDADMAC is usually delivered as a liquid concentrate having a solids level in the range of 10 to 50%. It is a high charge density cationicpolymer. The charge density makes it well suited for flocculation.
