In the papermaking industry, achieving effective wet-end chemistry is crucial for improving paper quality and process efficiency. One essential component driving this efficiency is DADMAC (Diallyldimethylammonium chloride), a high-purity cationic monomer used to synthesize PolyDADMAC—a widely used retention aid and trash catcher in paper manufacturing.
As demands for higher machine speeds and closed water loops increase, the performance of chemical additives becomes more important than ever. Understanding how DADMAC supports papermaking chemistry is key to optimizing your wet-end performance.
What is DADMAC?
DADMAC is a water-soluble quaternary ammonium salt, commonly used as a monomer in producing high-charge-density cationic polymers such as PolyDADMAC. Its molecular formula is C₈H₁₆ClN, and it is known for its:
- High cationic charge density
- Excellent water solubility
- Low molecular weight, making it highly reactive for polymerization
It plays a critical role in formulating polymers that are used as retention aids, coagulants, and fixatives in papermaking.
Application of DADMAC in Papermaking
DADMAC itself is not directly added to paper pulp; instead, it is polymerized into PolyDADMAC, which is then used in the wet-end to:
- Neutralize anionic trash
- Improve filler and fines retention
- Stabilize the paper machine system
- Reduce cationic demand
By controlling charge balance in the system, PolyDADMAC synthesized from high-quality DADMAC helps reduce the dosage of other expensive additives and improves drainage and retention efficiency.

Benefits of High-Purity DADMAC
Choosing a high-quality DADMAC monomer is vital for producing stable, high-performance polymers. Key advantages include:
- Low residual impurities
- High polymerization efficiency
- Consistent product quality in final PolyDADMAC
These features ensure that the final polymer has predictable performance in terms of charge density and molecular weight—both of which are critical in papermaking applications.
