Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-(2-Methyl-1-Oxo-2-Propenyl)-.Omega.-Hydroxy-, C16-18-Alkyl Ethers is a specialized reactive macromonomer belonging to the class of polymerizable surfactants and macromonomers. This compound is engineered to combine the surface-active properties of a C16-18 alkyl chain polyether with the polymerizable methacrylate functionality, enabling its covalent incorporation into polymer matrices. It is primarily utilized by formulators and polymer chemists in industries requiring advanced material performance, such as coatings, adhesives, and personal care, where it acts as a surfactant, stabilizer, or property-modifying co-monomer.

Application

• Emulsion Polymerization Stabilizer: Acts as a reactive surfactant (surfmer) in acrylic, styrene-acrylic, and vinyl acetate emulsion polymerizations, providing colloidal stability and becoming grafted into the polymer backbone for enhanced durability.
• Coatings & Inks: Used as a property modifier in radiation-curable (UV/EB) coatings, printing inks, and overprint varnishes to improve adhesion, flexibility, and surface wetting.
• Adhesives & Sealants: Incorporated into pressure-sensitive adhesives (PSAs) and structural adhesives to modulate tack, peel strength, and compatibility with various substrates.
• Personal Care Products: Serves as a polymerizable emulsifier or rheology modifier in advanced cosmetic formulations, such as long-wearing nail polishes and sunscreens.
• Composite Materials: Functions as a coupling agent or interfacial modifier in fiber-reinforced composites and nanoparticle dispersions to improve matrix-filler interaction.
• Lubricant & Fuel Additives: Employed as a dispersant and viscosity modifier in synthetic lubricants and fuel formulations.
