Description

2-(2-Hydroxyethoxy)Ethyl 2-Methyl-2-[(1-Oxoallyl)Amino]Propanesulphonate is a specialized reactive monomer and functional sulfonate compound. This chemical is valued for its dual functionality, incorporating both a polymerizable vinyl group and a hydrophilic sulfonate moiety, which is critical for imparting permanent ionic character and enhanced hydrophilicity to polymer chains. It is primarily sought by formulators and polymer chemists in the production of advanced materials requiring durable surface charge, antistatic properties, or improved adhesion to polar substrates. The compound, CAS 85169-24-0, is a key building block for high-performance coatings, hydrogels, and specialty adhesives.

Application

• Reactive Monomer for Functional Polymers: Used in the synthesis of acrylic and vinyl polymers to introduce permanent anionic (sulfonate) charges into the polymer backbone.
• Antistatic Agent Precursor: Incorporated into coatings and films for electronics packaging, synthetic fibers, and plastics to provide durable static dissipation.
• Hydrogel and Contact Lens Materials: Serves as a co-monomer to enhance water retention, oxygen permeability, and biocompatibility in hydrogel matrices.
• Adhesive and Sealant Formulations: Improves adhesion to difficult substrates (e.g., metals, glass) and enhances the ionic character of pressure-sensitive adhesives.
• Surface Modification of Nanoparticles: Acts as a stabilizer and surface charge modifier for inorganic nanoparticles in aqueous dispersions.
• Ion-Exchange Resins and Membranes: A key monomer for creating sulfonated polymers used in water purification, desalination, and fuel cell applications.
• Textile and Leather Auxiliaries: Imparts softness, dyeability, and antistatic properties in finishing formulations.
