Polyacrylamide (PAM) [CAS 9003-05-8] is a linear synthetic water-soluble polymer built from acrylamide monomers. In the case of Anionic Polyacrylamide (APAM), the polymer chain is synthesized via copolymerization of acrylamide with negatively charged acrylic acid monomers or through partial hydrolysis of polyacrylamide with sodium hydroxide.
The chemical structure features repeating acrylamide units alongside acrylate carboxylate groups ($-\text{COO}^-\text{Na}^+$). The degree of hydrolysis determines the negative charge density, while control over chain propagation yields ultra-high molecular weights ranging from 5 Million to upwards of 25 Million Daltons (g/mol). This dual-function molecular architecture enables APAM to operate through two primary physical-chemical mechanisms: electrostatic charge neutralization and macromolecular bridging.
| Specification Parameter | Typical Industrial Range | Operational Function & Application Impact |
|---|---|---|
| Molecular Weight (MW) | 5 Million - 25 Million Daltons | Higher MW increases long-chain bridging capacity, creating larger, faster-settling flocs in mineral tailings and wastewater. |
| Degree of Hydrolysis (Charge Density) | 10% - 60% (Low, Medium, High) | Regulates ionic charge interaction with positively charged suspended solids, clay minerals, and metal hydroxides. |
| Solid Content | ≥ 88% - 90% (Powder Granules) | Ensures high active polymer concentration, optimizing freight efficiency and dissolution yield. |
| Dissolution Time | ≤ 45 - 60 Minutes (in ambient water) | Rapid solubilization profile reduces aging tank energy consumption and prevents gel-block formation. |
| Residual Monomer | ≤ 0.05% (500 ppm max) | Ultra-low free monomer level ensures compliance with strict environmental regulations and potable water standards. |
In aqueous suspensions, fine suspended particles often exhibit weak negative surface charges that cause mutual repulsion, preventing gravitational settling. When high-molecular-weight Anionic Polyacrylamide is introduced into an alkaline or neutral aqueous medium:

Tailored APAM formulation strategies engineered for complex global industries.
As a vital flocculating agent, APAM drives solid-liquid separation in municipal sewage treatment and diverse industrial effluents (leather, citric acid, pharmaceutical, vegetable protein extract, incense, and dyeing). Increasingly strict environmental regulations drive high-efficiency dewatering and water reuse requirements worldwide.
APAM serves as a retention agent, filter aid, and dry strength agent in paper mills. It increases retention of short fibers and fillers, enhances paper tensile strength, neutralizes anionic trash in white water, and accelerates deinking process flocculation.
Extensively utilized in tertiary Enhanced Oil Recovery (EOR), profile control, plugging agents, and fracturing fluids. APAM reduces drilling fluid friction loss, inhibits shale swelling, cools drill bits, carries cuttings, and optimizes oil sands solid removal.
Used for coal washing, tailings dewatering, and solid-liquid separation across gold, silver, iron, copper, and alumina operations. APAM speeds up thickener sedimentation and centrifuge filtration while recycling process water back to the mill.
High-purity APAM food-grade formulations promote rapid clarification and flotation during sugarcane and sugar beet juice extraction, efficiently precipitating organic impurities without contaminating final sugar crystals.
APAM acts as a high-performance sizing agent, finishing agent, and fabric treatment auxiliary. In textile wastewater systems, it effectively removes intense dyes, suspended solids, and heavy metals via rapid flocculation.
