At NINGBO INNO PHARMCHEM CO.,LTD., we believe in empowering our clients with a deep understanding of the chemicals we supply. Diallyldimethylammonium Chloride (DADMAC) is a fascinating molecule whose scientific properties underpin its widespread industrial utility. As a cationic monomer, its structure and reactivity are key to its performance in applications ranging from textile treatment to advanced water purification.

Chemically, DADMAC is a quaternary ammonium salt with the molecular formula C8H16ClN. Its most defining characteristic is the permanent positive charge conferred by the quaternary ammonium group. This cationic nature is central to its function as a flocculant, retention aid, and conditioning agent. DADMAC is typically supplied as an aqueous solution, often at concentrations of 60% or 65%, and is readily soluble in water. It is also noted for its stability at room temperature, its non-flammable nature, and its low irritation to the skin, making it safer to handle compared to many industrial chemicals.

The real power of DADMAC emerges through its polymerization capabilities. The molecule contains two vinyl groups (alkenyl double bonds), which are highly reactive and can undergo free-radical polymerization. This allows DADMAC to form linear homopolymers, where multiple DADMAC units link together. More importantly, it can copolymerize with other vinyl monomers, creating a vast array of polymers with tailored properties. The resulting polymers inherit the cationic charge from the DADMAC units, and their specific characteristics—such as molecular weight, charge density, and branching—can be controlled by the polymerization conditions and the choice of comonomers.

These DADMAC-based polymers are the actual workhorses in many applications. In water treatment, they act as highly efficient coagulants and flocculants due to their high charge density, effectively neutralizing colloidal suspensions. In textiles, the cationic polymers form films that improve dye uptake and colorfastness. In papermaking, these polymers bind fibers and fillers, enhancing strength and drainage. The ability to fine-tune polymer properties through controlled polymerization makes DADMAC an invaluable building block for advanced chemical formulations.

NINGBO INNO PHARMCHEM CO.,LTD. is committed to supplying DADMAC that adheres to strict purity and quality standards, ensuring reliable polymerization outcomes for our clients.
