Poly(dimethyldiallylammonium chloride); Polyquaternium-6
Poly(diallyldimethylammonium 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.
Poly(diallyldimethylammonium chloride) is usually delivered as a liquid concentrate having a solids level in the range of 10 to 50%.
Poly(diallyldimethylammonium chloride) is a high charge density cationic polymer.
The charge density makes Poly(diallyldimethylammonium chloride) well suited for flocculation.
History of Poly(diallyldimethylammonium chloride)
Poly(diallyldimethylammonium chloride) polymers were first prepared and studied in 1957 by Professor George Butler at the University of Florida.
Poly(diallyldimethylammonium chloride) 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.
Synthesis of Poly(diallyldimethylammonium chloride)
The monomer Poly(diallyldimethylammonium chloride) is formed by reacting two equivalents of allyl chloride with dimethylamine.
Poly(diallyldimethylammonium chloride) is then synthesized by radical polymerization of DADMAC with an organic peroxide used as a catalyst.
Two polymeric structures are possible when polymerizing DADMAC: N-substituted piperidine structure or N-substituted pyrrolidine structure.
The pyrrolidine structure is favored.
