Description
Sodium vinylsulfonate (CAS 3039-83-6, EC 221-242-5) is a reactive sulfonate monomer supplied as a 30% aqueous solution. It is also known by trade names including Tamol VS, N-SVS 25, and HS 1. No E-code applies; the material is classified under HS code 2904.10.5000.
In polymer manufacturing, sodium vinylsulfonate is copolymerised with acrylic or other vinyl monomers to introduce permanent sulfonate groups into polymer chains, improving hydrophilicity and antistatic performance in textile and paper coatings. In water treatment, it functions as a scale-inhibiting comonomer in dispersant polymers that prevent mineral deposition on process equipment surfaces.
The standard commercial grade is a 30% aqueous solution conforming to REACH registration requirements for the European market. Procurement teams should confirm supplier SDS documentation and REACH compliance status prior to ordering. Packaging is typically available in drums and IBC containers.
