Description
Sodium Methallyl Sulfonate (CAS 1561-92-8, EC 216-341-5, formula C4H8O3S.Na) is a sulfonate-functional monomer also referenced as SMAS in polymer chemistry. It carries no assigned E-code and is commercially available as a 35% aqueous solution under the trade designation sodiummethallylsulfonate(35%).
In acrylic and polyester fiber production, Sodium Methallyl Sulfonate is copolymerized into polymer backbones to introduce permanent anionic sulfonate groups, improving dye uptake and antistatic performance. In water treatment and textile processing, its sulfonate functionality also contributes antimicrobial and scale-inhibiting properties within formulated systems.
Sodium Methallyl Sulfonate is supplied in powder-to-crystal form and as a 35% aqueous solution, with grades suitable for industrial polymer and water treatment applications. The substance is registered under REACH and classified under HS code 2904.10.5000. Buyers should confirm grade specifications and SDS documentation prior to procurement.
