Full Description

Poly(diallyldimethylammonium chloride) (CAS 26062-79-3) is a high-charge cationic polymer supplied as an aqueous solution. It is used as a primary coagulant and charge-neutralizing flocculant in drinking-water and wastewater treatment and as a charge-control additive in papermaking.

Frequently Asked Questions

What is PolyDADMAC used for?

PolyDADMAC (poly(diallyldimethylammonium chloride)) is used as a primary coagulant and charge-neutralizing flocculant in drinking-water and wastewater treatment. It is also used as a charge-control and retention additive in papermaking and for sludge conditioning to improve dewatering.

Is PolyDADMAC a coagulant or flocculant?

It functions primarily as a cationic coagulant: its high positive charge density neutralizes and destabilizes anionic colloids and turbidity. Depending on molecular weight and dose it can also contribute flocculation by bridging destabilized particles into settleable flocs.

What is another name for PolyDADMAC?

It is also known by its full chemical name, poly(diallyldimethylammonium chloride), and abbreviations such as pDADMAC or PDADMAC. The CAS number is 26062-79-3.

Is PolyDADMAC organic?

Yes, it is a synthetic organic cationic polymer (a quaternary ammonium polyelectrolyte) supplied as an aqueous solution. The quaternary nitrogen carries the fixed positive charge responsible for its coagulation performance.

How is bulk PolyDADMAC supplied and priced?

It is supplied as an aqueous solution in bulk packaging such as drums, totes, and IBCs; solution actives content varies by grade. Pricing depends on concentration, molecular weight, and volume, so request a bulk quote with your target spec for current pricing and a CoA.
