Performance and application of SSS/MA

• Name: Sodium Styrene Sulfonate/Maleic Anhydride Copolymer (SSS/MA)

• Type: Water-soluble anionic polymer

• Structure: Alternating copolymer of sodium styrene sulfonate (SSS) and maleic anhydride (MA).

• Appearance: White to off-white powder or aqueous solution.

• Solubility: Highly soluble in water, forms clear solutions.

• Effective against:

• Calcium carbonate (CaCO?)

• Calcium sulfate (CaSO?)

• Iron oxide (Fe?O?/Fe?O?)

• Mechanism: Adsorbs onto crystal surfaces, inhibiting growth and agglomeration.

• Temperature resistance: Stable up to ~90°C (higher than polyacrylic acid).

• pH range: Effective in neutral to alkaline conditions (pH 7–10).

• Works synergistically with:

• Organic phosphonates (e.g., HEDP, ATMP)

• Zinc salts (for corrosion inhibition).

• Cooling water systems: Prevents scale and disperses suspended solids.

• Boiler water: Controls phosphate/calcium sludge.

• RO membranes: Antiscalant for high-sulfate waters.

• Builder function: Enhances detergent efficiency by sequestering Ca2?/Mg2?.

• Drilling fluids: Disperses clay particles.

• Enhanced oil recovery (EOR): Improves polymer flood stability.

• Dye dispersion: Prevents agglomeration in textile processing.

• Paper coatings: Improves filler retention.

• Cooling water: 5–20 mg/L.

• Detergents: 0.1–2% of formulation.

• Oilfield fluids: 0.5–5 kg/ton of dry clay.

• Biodegradability: Partial (slower than PAA).

• Regulatory: Compliant with EPA and REACH standards.

Conclusion: SSS/MA excels in high-temperature, high-iron, and alkaline water systems, offering superior dispersion and scale control. Ideal for industries requiring robust performance under harsh conditions.
