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.

Usages: 

- PolyDADMAC can be used in dyeing and nishing auxiliaries as advanced formaldehyde-free color-xing agent, and can form lm in the fabric and improve color fastness.
- PolyDADMAC can be used in papermaking, coating and antistatic agent, AKD sizing promoter and retention and drainage agent. 
- PolyDADMAC also can be used in decolor, occulate in water treatment (drinking and waste water). - In daily chemical, PolyDADMAC can be use as shampoo carding agent, wetting agent and antistatic agent. 
- In the oil eld chemicals, the PolyDADMAC can be used in clay stabilizer, acid fracturing cation additive etc. 

When used alone, PolyDADMAC should be diluted to the concentration of 0.5%-0.05% (based on solid content). When PolyDADMAC be used to treat dierent source water or waste water, the dosage is based on the turbidity and the concentration of the water. The most economical dosage is based on the trial. The dosing spot and the mixing velocity should be carefully decided to guarantee that the chemical can be mixed evenly with the other chemicals in the water and the ocs can not be broken. It is better to dose the product continuously.

Properties: 

This DADMAC formulation is a high purity, quaternary ammonium salt monomer of water-soluble, high eciency, positively charged ions. Molecular formula C8H16NCl, molecular weight 161.5. Its molecular structure contains alkyl double bonds, which may form linear homopolymer and various kinds of copolymer through various kinds of polymer reactions. Features of DADMAC are that under normal temperature, it is quite stable, unhydrolyzed, nonammable with small excitability to skin and low toxicity.

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 occulation.

History 

PolyDADMAC polymers were rst prepared and studied in 1957 by Professor George Butler at the University of Florida.[1] 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.

Synthesis

The monomer DADMAC is formed by reacting two equivalents of allyl chloride with dimethylamine. PolyDADMAC is then synthesized by radical polymerization of DADMAC with an organic peroxide used as a catalyst. Two polymeric structures are possible when polymerizing DADMAC: Nsubstituted piperidine structure or N-substituted pyrrolidine structure. The pyrrolidine structure is favored.

Applications 

Euent 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.

Pulp and paper industry 

PolyDADMAC is used for controlling disturbing substances in the papermaking process. It provides superior xing 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 eciency of disk lters and otators, and for cationization of llers to provide maximal ller retention.

Water Purication

PolyDADMAC is used as a coagulant in water purication. It is eective in coagulating and occulating 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.

Polydiallyldimethylammonium chloride (PolyDADMAC) is a homopolymer of diallyldimethylammonium chloride (DADMAC), well known as one part of our Superoc C-500 series. These organic coagulants are liquid, cationic polymers of diering molecular weights. They work eectively as primary coagulants and charge neutralization agents. 

PolyDADMAC is often used in ltration applications or in conjunction with our occulant products. These polymers are highly eective in many water treatment clarication processes. PolyDADMAC and/or cationic polyamines can also be used in combination with our occulant and coagulant products to lower overall treatment costs.

PolyDADMAC (PD) is a high charge density cationic polymer of diallyldimethylammonium chloride which has been recently developed as a coagulant in water purication. As PD has high anity to ne negatively-charged colloids, it is worth to ascertain if PD can aect surface properties of clay-size particles in red mud waste and be applied to develop immobilization techniques for red mud storage areas. In the current study, a test tube method in combination with surface charge measurement was used for determination of the colloidal properties of a red mud sample under the variation of PD, soluble Al and Si, and variable pH conditions. 

Observations for the PD concentration range from 0.25 to 2.0 revealed that PD can increase surface charge and enhance aggregation or at least shift the aggregation zone to higher pH. This suggests a possible application of PD for immobilization of red mud in alkaline condition. It was also found that soluble Al and Si acted to modify the eect of PD and aggregation properties of red mud. While soluble Si supported aggregation, Al appeared as an enhancer for dispersion of red mud. It implies that development of PD-based techniques for immobilization of red mud needs to consider the eects of soluble Al and Si.
