As polymer formulation standards keep upgrading worldwide, manufacturers are continuously seeking stable functional co-monomers to enhance dispersion, salt tolerance and long-term stability of finished products. Among numerous sulfonate monomers, Sodium Methallyl Sulfonate (SMAS) stands out as a cost-effective, multi-purpose building block trusted by concrete admixture factories, textile fiber manufacturers, water treatment chemical enterprises and oilfield additive producers.
Sodium Methallyl Sulfonate, short name SMAS, CAS 1561-92-8, owns unique molecular structure: reactive C=C double bond plus hydrophilic sulfonate group \(-SO_3Na\). Compared with Sodium Allyl Sulfonate (SAS), the methyl branch brings stronger steric hindrance. This structural advantage delivers excellent slump retention, thermal stability and anti-electrolyte performance, solving many typical pain points in copolymerization.
Sentai provides two mainstream grades to match different production workflows:
✅ 99.5% High-purity crystalline powder
Low chloride and sulfate impurities, stable polymerization activity. Ideal for polycarboxylate superplasticizer, PAN carbon fiber precursor and high-end emulsion polymerization.
✅ 35% Aqueous SMAS liquid
Ready to feed without dissolution, suitable for continuous liquid synthesis of water treatment dispersants, coating additives and drilling fluid polymers, saving labor and simplifying production.
Core Application Areas
- Polycarboxylate Superplasticizer Raw MaterialCopolymerized with polyether macromonomer to synthesize third-generation PCE superplasticizer. Improve water reduction rate and slump retention, widely used in high-speed railway, bridge, precast concrete and UHPC projects.
- Third Monomer for Acrylic PAN FiberIntroduce anionic groups into fiber chains, greatly improve dye uptake, color fastness, anti-static property and spinnability. Also applied for PAN carbon fiber precursor production.
- Water Treatment Scale Inhibitor & Dispersant MonomerSynthesize acrylic copolymer scale inhibitors, suppress calcium carbonate and phosphate scaling under high temperature & high salinity circulating water systems.
- Oilfield ChemicalsManufacture temperature-resistant fluid loss control agents and polymer flooding additives, resist interference from calcium and magnesium ions in formation water.
- Other Fields: Waterborne coating dispersants, papermaking dry strength agents, ion exchange resin raw materials
