Poly diallyldimethyl ammonium chloride (shortened polyDADMAC or polyDDA) 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.

Application:
1. Effluent treatment
PolyDADMAC is used in
waste water treatment as a primary organic
coagulant which neutralizes
negatively charged colloidal material and reduces
sludge volume compared with
inorganic coagulants.
2. Pulp and paper industry
PolyDADMAC is used for controlling disturbing substances in the
papermaking process. It provides superior
fixing of pitch from
mechanical pulp and of
latex from coated broke. Used in the short circulation of a
paper mill to enhance
retention and
dewatering. In addition, it can be used to improve the efficiency of disk filters and flotators, and for
cationization of
fillers to provide maximal filler retention.
3.
Water purification
PolyDADMAC is used as a coagulant in
water purification. It is effective in coagulating and flocculating inorganic and organic particles such as silt, clay, algae, bacteria and viruses. At high concentrations the organic polymer can remove natural organic matter such as
humic and fulvic acids resulting in fewer
disinfection byproduct precursors and less color.
