Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-(2-Methyl-1-Oxo-2-Propenyl)-.Omega.-2,4,6-Tris(1-Phenylethyl)Phenoxy- is a specialized macromonomer or functionalized polymer surfactant, designed to impart specific surface-active and reactive properties. Its unique structure, featuring a poly(ethylene glycol) (PEG) backbone capped with a methacrylate group and a bulky, sterically hindered phenolic group, makes it a valuable reactive intermediate and stabilizer in advanced polymer synthesis. This chemical is essential for manufacturers in the coatings, adhesives, and specialty polymer industries seeking to create materials with tailored hydrophilicity, cross-linking capability, and enhanced stability.

Application

• UV-Curable Coatings & Inks: Acts as a reactive diluent and macromonomer to modify viscosity, enhance film flexibility, and improve adhesion properties.
• Advanced Polymer Synthesis: Serves as a functional initiator or chain transfer agent in controlled radical polymerization (e.g., ATRP, RAFT) to create block or graft copolymers.
• Surface Modification Agent: Used to graft hydrophilic PEG chains onto surfaces or particles, improving biocompatibility, reducing protein adsorption, or creating anti-fouling coatings.
• Dispersant & Stabilizer: The bulky phenolic end-group provides steric stabilization for pigments, nanoparticles, or resins in formulations, preventing aggregation.
• Adhesive & Sealant Formulations: Imparts toughness and weatherability while maintaining processability in high-performance adhesive systems.
• Biomedical Materials: Potential use in the synthesis of hydrogels or drug delivery systems where a polymerizable PEG derivative is required.
