Composition: The name of this chemical says it all. It is a linear homopolymer formed from a monomer that has a quaternary ammonium and two unsaturated -CH=CH2 functionalities. The monomer itself is formed by reacting two equivalents of allyl chloride with dimethylamine. Free-radical polymerization of the “DADMAC” monomers yields a structure in which the quaternary ammonium groups are on rings that are included in the backbone of the polymer chain. This composition means that the poly-DADMAC macromolecules tend to be quite stiff, having a longer persistence length than, for instance, polyamines. For this reason, poly-DADMAC is expected to have a more extended conformation in solution. The molecular weight of DADMAC is typically in the range of hundreds of thousands of grams per mole, and even up to a million for some products. DADMAC is usually delivered as a liquid concentrate having a solids level in the range of 10 to 50%.

Usages:

– PolyDADMAC can be used in dyeing and finishing auxiliaries as advanced formaldehyde-free color-fixing agent, and can form film 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, flocculate 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 field 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 different 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 flocs can not be broken. It is better to dose the product continuously.

Effective at low dosages

Easy to prepare solution and apply

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.

History

PolyDADMAC polymers were first 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: N-substituted piperidine structure or N-substituted pyrrolidine structure. The pyrrolidine structure is favored.

Applications

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.

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.

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.

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

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

POLY DADMAC

Polyelectrolytes for treatment of water from various processes. We offers top quality products, services and solution to all water related needs of various industries.

Poly DADMAC polymer is used to supplement liquid alum in the coagulation process and its use is essential in ensuring that the stringent water quality standards are met. With the addition of Poly DADMAC polymer, alum and caustic soda usage has dropped and the production of sludge has been reduced.

Poly DADMAC is used as flocculant in water purification. It is very effective in flocculating, decoloring, killing algae and removing organics such as humus. Little is needed to produce large flocs, rapid precipitation and low turbidity residue.

Uses of PolyDADMAC

1. Effluent treatment

Poly DADMAC 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

Poly DADMAC can also be used as a flocculant to improve soap separation process in the evaporation plant of kraft pulp mills thus contributing to higher tall oil yield.

3. Water purification

PolyDADMAC (PD) is a high charge density cationic polymer of diallyldimethylammonium chloride which has been recently developed as a coagulant in water purification. As PD has high affinity to fine negatively-charged colloids, it is worth to ascertain if PD can affect 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?mM 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 effect 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 effects of soluble Al and Si.

Poly(diallyldimethylammonium chloride) (polyDADMAC) has been shown to be an important precursor of the probable human carcinogen -nitrosodimethylamine (NDMA) when in contact with chloramine. In this study, we conducted an orthogonal experiment design to evaluate the effects of pH values, ammonia, bromide, natural organic matter (NOM) and monochloramine dosages on the formation of NDMA from polyDADMAC during chloramination. Meanwhile, single-factor experiments of pH, bromide and NOM prove the results of orthogonal experiment. The results supported that pH was the most critical factor affecting NDMA formation from polyDADMAC during chloramination, and the highest NDMA formation from polyDADMAC occurred at pH near 7 due to released DMA from polyDADMAC degradation and the critical importance of low concentrations of dichloramine in water. In the presence of excess bromide, the NDMA formation was enhanced significantly at all different pH values owing to bromochloramine, which has higher electronegativity of the brominated nitrogen atom than monochloramine or dichloramine. The NDMA formation from polyDADMAC in the presence of NOM was 41.7% lower than NDMA formation in the absence of NOM. The overwhelming majority of NDMA formation from polyDADMAC under simulated conditions was lower than the current advisory levels (i.e. 9?ng?l in Ontario, 10?ng?l in California).

Bu çalmada, PD, çözünür Al ve Si varyasyonlar ve deiken pH koullar altnda krmz bir çamur numunesinin kolloidal özelliklerinin belirlenmesi için yüzey yükü ölçümü ile birlikte bir test tüpü yöntemi kullanlmtr. PD konsantrasyonu için 0.25 ila 2.0 mM arasndaki gözlemler, PD’nin yüzey yükünü artrabildiini ve toplanmay artrabileceini veya en azndan toplanma bölgesini daha yüksek pH’a deitirebileceini ortaya koydu. Bu, alkali durumda krmz çamurun immobilizasyonu için PD’nin olas bir uygulamasn önerir. Ayn zamanda, çözünür Al ve Si’nin, PD’nin etkisini ve krmz çamurun toplanma özelliklerinin deitirilmesinde etkili olduu bulunmutur. Çözünebilir Si destekli agregasyon olsa da, Al krmz çamurun dalmas için bir güçlendirici olarak göründü. Krmz çamurun hareketsiz hale getirilmesi için PD bazl tekniklerin gelitirilmesinin, çözünür Al ve Si’nin etkilerini göz önünde bulundurmas gerektii anlamna gelir.

L’histoire

Polymères PolyDadmac ont d’ abord été préparés et étudiés en 1957 par le professeur George Butler à l’Université de Floride. Il est remarquable car il est soluble dans l’ eau, contrairement à l’époque à d’ autres polymères synthétiques connus formés par polymérisation de monomères contenant plus d’une fonctionnalité vinyle. Le chemin de la structure et la réaction a été déterminée en 2002 par RMN études.

Steepto

Synthèse

Le monomère DADMAC est formé en faisant réagir deux équivalents de chlorure d’allyle avec la diméthylamine . PolyDADMAC est ensuite synthétisé par polymérisation radicalaire de DADMAC avec un matériau organique de peroxyde utilisé comme catalyseur . Deux structures polymères sont possibles lors de la polymérisation DADMAC: N -substitué pipéridine structure ou la N -substitué pyrrolidine structure. La structure pyrrolidine est favorisée.

Applications

traitement des eaux usées

PolyDADMAC est utilisé dans le traitement des eaux usées en tant que primaire organique coagulant qui neutralise chargé négativement colloïdale matériau et réduit les boues de volume par rapport aux inorganiques coagulants.

L’industrie des pâtes et papiers

PolyDADMAC est utilisé pour contrôler des substances perturbatrices dans le papier processus. Il offre une meilleure fixation de pas de pâte mécanique et de latex de revêtement cassé. Utilisé dans la circulation courte d’une usine de papier pour améliorer la rétention et la déshydratation . De plus, il peut être utilisé pour améliorer l’efficacité des filtres à disques et flottateurs, et pour cationisation des charges pour assurer une rétention maximale de remplissage.

Purification de l’eau

PolyDADMAC est utilisé comme coagulant dans la purification de l’ eau . Il est efficace pour coaguler et floculer des particules inorganiques et organiques tels que le limon, l’ argile, les algues, les bactéries et les virus. A des concentrations élevées , le polymère organique peut éliminer les matières organiques naturels tels que les acides humique et fulvique résultant en moins de sous – produits de désinfection précurseurs et moins de couleur.
