Sodium vinylsulfonate

Sodium vinylsulfonate (CAS 3039-83-6), commonly abbreviated as SVS, is a reactive monomer used as a building block in polymer synthesis and surface modification chemistry. It introduces permanent sulfonate functionality into polymer chains, enabling performance characteristics that drive demand across water treatment, textile processing, and specialty coatings.

In water treatment, SVS is copolymerized into scale inhibitors and dispersants that prevent mineral deposit buildup in industrial cooling systems and boilers. Textile and paper processors incorporate SVS-based polymers to improve dye uptake uniformity and wet fastness on fiber surfaces during the manufacturing process.

In the plastics and polymer industry, it functions as a comonomer in the production of ion-exchange resins, antistatic coatings, and hydrophilic membrane materials. Leather finishing formulations use SVS copolymers to achieve durable surface treatments with improved adhesion and water resistance for high-quality consumer goods.

Sodium vinylsulfonate is supplied as an aqueous solution, typically at 25% or 30% active content, which is the standard commercial form for handling and direct use. Technical grade is the predominant specification available in the market. It is packaged in drums and intermediate bulk containers suited to industrial procurement volumes.
