Polyquaternium 6 is used as a coagulant aid in water treatment.
PDADMAC can be used as an electrolytic solution in a variety of applications such as drug delivery, biomedical systems, and sensors, which include biosensors and chemical sensors.
Poly(diallyldimethylammonium chloride) solution (PDADMAC) is a cationic polyelectrolyte that is widely utilized as a flocculant. It is prepared by the radical polymerization of diallyldimethylammonium chloride (DADMAC) in presence of a catalyst in the form of an organic peroxide.
Precipitate it from water with acetone, and dry the salt in a vacuum for 24hours. [Hardy & Shriner J Am Chem Soc 107 3822 1985.]
