Poly(diallyldimethylammonium chloride) NEW

Polydiallyldimethylammonium 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.

Appearance and properties: liquid

Density: 1.04 (20% aq.)

Boiling point: 100ºC

Flash point: 100ºC

Refractive index: 1.375

Stable. Incompatible with strong oxidizing agents, iron and iron salts, steel, copper, copper alloys, aluminium.

Usage:Widely used in water treatment industry, the copolymer is an excellent cationic organic polymer flocculant. It has a wide range of charge densities, with cationic monomers accounting for a molar fraction of the copolymer from 10% to 58%, and high molecular weights. It can act as both charge neutralization and bridging flocculation.
