Sign in to saveAlso known as polyquaternium-6, poly(dimethyldiallylammonium chloride
Polydiallyldimethylammonium chloride (shortened polyDADMAC or polyDDA), also commonly polyquaternium-6, is a homopolymer of diallyldimethylammonium chloride (DADMAC). The molecular weight of polyDADMAC is typically in the range of hundreds of thousands of grams per mole, and even 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 cationic polymer. The charge density makes it well suited for flocculation. Actually, pDADMAC or DMDAAC, is used as a coagulant - a charge neutralizati

Polydiallyldimethylammonium chloride (shortened polyDADMAC or polyDDA), also commonly polyquaternium-6, is a homopolymer of diallyldimethylammonium chloride (DADMAC). The molecular weight of polyDADMAC is typically in the range of hundreds of thousands of grams per mole, and even 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 cationic polymer. The charge density makes it well suited for flocculation. Actually, pDADMAC or DMDAAC, is used as a coagulant - a charge neutralization process that precedes flocculation.
==History== PolyDADMAC polymers were first prepared and studied in 1957 by Professor George Butler at the University of Florida. It was remarkable as it was soluble in water in contrast at the time to other known synthetic polymers formed by polymerization of monomers containing more than one vinyl functionality. The structure and reaction path was determined in 2002 with NMR studies. Much of what we know about pDADMAC in water treatment and personal care is from Jerry Boothe of Calgon Corporation.
