As polymer formulation technology keeps upgrading across construction, textile, water treatment and oilfield sectors, R&D engineers are constantly seeking reliable functional monomers to boost product stability, salt tolerance and dispersion performance. Among numerous sulfonate co-monomers, Sodium Methallyl Sulfonate (SMAS) stands out as a cost-effective, multi-purpose building block trusted by manufacturers worldwide.
Sodium Methallyl Sulfonate, abbreviated SMAS, CAS 1561-92-8, carries a unique molecular structure combining reactive carbon-carbon double bond and hydrophilic sulfonate group \(-SO_3Na\). Unlike ordinary sodium allyl sulfonate (SAS), the methyl branch on its carbon chain creates stronger steric hindrance. This structural advantage delivers outstanding slump retention, high-temperature stability and anti-electrolyte capacity, solving many common pain points in copolymer synthesis.
Our factory supplies two mainstream commercial grades to match diverse production processes:
99.5% High-purity crystalline powder
Suitable for polycarboxylate superplasticizer, PAN carbon fiber precursor and high-end emulsion polymerization. Low impurity content, stable polymerization activity, effectively avoiding abnormal crosslinking and yellowing of finished polymers.
35% Aqueous SMAS liquid
Ready-to-use without dissolution, ideal for continuous liquid-phase production of water treatment dispersants, coating additives and oilfield chemicals. Save labor costs and simplify feeding procedures.
Wide Application Scenarios to Empower Your Production
1. Polycarboxylate Superplasticizer Raw Material (Largest Consumption Field)
Copolymerized with polyether macromonomer and unsaturated carboxylic acid to synthesize third-generation polycarboxylate superplasticizer. The sulfonate groups provide electrostatic repulsion and steric dispersion effect, improving water reduction rate and long-term slump retention. Perfect for high-speed rail, bridge, precast components and ultra-high-performance concrete projects.
2. Third Monomer for Acrylic Fiber
In PAN acrylic fiber production, SMAS introduces anionic groups into polymer chains. It significantly improves fiber dye uptake, color fastness, anti-static property and spinnability. It is also widely adopted as key raw material for PAN-based carbon fiber precursor to optimize molecular weight distribution.
3. Water Treatment Scale Inhibitor & Dispersant Monomer
Copolymerized with acrylic acid and acrylamide to produce circulating water scale inhibitors. Effectively suppress calcium carbonate, calcium phosphate deposition under high temperature and high salinity conditions, widely used in power plants, steel mills and chemical cooling water systems.
4. Oilfield Chemical Additives
Used to synthesize temperature-resistant fluid loss agents and polymer flooding agents. The sulfonate structure resists interference from calcium and magnesium ions in formation water, stabilizing drilling fluid properties in deep wells.
5. Other Fine Polymer Fields
Water-based acrylic coating dispersants, papermaking dry strength agents, ion exchange resins and functional emulsion additives.
