Description

General description

Diallyldimethylammonium chloride (DADMAC) is a quaternary ammonium compound available in solid form with an assay of ≥97.0%. It serves as a versatile monomer in various polymerization processes and is primarily used in the production of cationic polymers. These polymers are essential in a range of applications, particularly in the fields of water treatment, paper production, and personal care products. Additionally, DADMAC exhibits antifouling properties, making it valuable for applications where the prevention of biofilm formation and surface fouling is critical.

Application

Diallyldimethylammonium chloride can be used as:

• A precursor for the synthesis of poly(diallyldimethylammonium chloride) (PDADMAC), which is widely used in various applications related to water purification and wastewater management.
• a monomer in the synthesis of cationic hydrogels via radical polymerization. The resulting polymer, poly(diallyldimethylammonium chloride) (PDADMAC), features a high cationic charge density, which is crucial for effectively binding anionic dyes. This property makes PDADMAC-based hydrogels valuable materials for wastewater treatment applications.
• DADMAC has been used in dental biomaterials to enhance their antifouling properties. When incorporated into acrylic resins, it provides effective antibacterial and antifungal activity without compromising biocompatibility
