General Description
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.
Synthesis
The monomer DADMAC is formed by reacting two equivalents of allyl chloride with dimethylamine.Poly(diallyldimethylammonium chloride) 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.

Purification Methods
Precipitate it from water with acetone, and dry the salt in a vacuum for 24hours. [Hardy & Shriner J Am Chem Soc 107 3822 1985.]
Toxics Screening Level
The initial threshold screening level (ITSL) for polydimethyl diallyl ammonium chloride is 1000 μg/m3 (annual averaging time) based on the Michigan Department of Environmental Quality (MDEQ).
