The effectiveness of industrial chemicals often lies in their underlying chemical structure and properties. Poly(diallyldimethylammonium chloride), commonly known as PolyDADMAC, is a prime example. Identified by its CAS number 26062-79-3, this cationic polymer is celebrated for its versatility and performance across a range of critical industrial applications. NINGBO INNO PHARMCHEM CO.,LTD., a prominent manufacturer and supplier, is here to unpack the chemistry and applications that make PolyDADMAC an indispensable chemical intermediate.

At its core, PolyDADMAC is a homopolymer derived from the diallyldimethylammonium chloride (DADMAC) monomer. The polymerization process creates long polymer chains where each repeating unit carries a quaternary ammonium group. This positive charge is what defines PolyDADMAC as a cationic polymer. This inherent positive charge is the key to its functionality in many applications, particularly in processes involving negatively charged substances.

In water treatment, the cationic nature of PolyDADMAC allows it to effectively neutralize the negative charges of colloidal particles, suspended solids, and dissolved organic matter in water. This process, known as charge neutralization, destabilizes these impurities, causing them to aggregate into larger flocs. These larger flocs are then more easily removed through sedimentation or filtration, leading to purified water. Its ability to act as both a coagulant and a flocculant makes it a highly efficient choice for wastewater treatment, industrial process water, and even potable water purification. When looking to buy PolyDADMAC for these uses, understanding the required molecular weight (indicated by viscosity) is important for optimal performance.

Beyond water purification, the cationic charge of PolyDADMAC also finds utility in the textile industry. It acts as a formaldehyde-free color-fixing agent, binding dye molecules to fabric fibers and improving color fastness. In papermaking, it enhances retention of fillers and fines and improves drainage, contributing to better paper quality and reduced processing costs.
