Description

Poly(Ethylene Glycol) 4-Nonylphenyl Ether Acrylate, Average Mn Ca. 450 is a reactive, non-ionic surfactant monomer designed for polymer synthesis. This compound is valued for its ability to impart amphiphilic character, surface activity, and UV-curability to polymeric materials. It is an essential raw material for formulators and polymer chemists in industries such as coatings, adhesives, and advanced material science.

Application

• UV-Curable Coatings & Inks: Acts as a reactive diluent and surfactant to enhance flow, adhesion, and surface wetting properties in radiation-curable systems.
• Acrylic Polymer Modification: Used to synthesize specialty acrylic copolymers with built-in surfactant functionality for improved emulsification and dispersion stability.
• Adhesives & Sealants: Incorporated to modify rheology, improve substrate wetting, and introduce cross-linking sites in pressure-sensitive and structural adhesive formulations.
• Dispersing Agent: Serves as a polymerizable dispersant in the production of pigment concentrates and nanoparticle suspensions.
• Hydrophilic Surface Modification: Employed to graft hydrophilic poly(ethylene glycol) chains onto surfaces, reducing protein adsorption and improving biocompatibility.
• Emulsion Polymerization: Functions as a reactive surfactant or co-monomer to stabilize latex particles and become chemically incorporated into the polymer matrix.
