Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-(2-Methyl-1-Oxo-2-Propenyl)-.Omega.-(Phosphonooxy)- is a specialized functional polymer, known commercially as a reactive macromonomer or polymerizable surfactant. Its core value lies in its unique bifunctional structure, combining a polymerizable methacrylate end-group with a terminal phosphonooxy moiety, enabling it to act as a crosslinker, dispersant, or surface modifier. This compound is essential for industries requiring advanced material performance, particularly in the formulation of high-performance coatings, adhesives, and specialty polymers where enhanced adhesion, dispersion stability, and crosslinking density are critical.

Application

• UV-Curable Coatings & Inks: Serves as a reactive oligomer to improve crosslinking efficiency, adhesion to difficult substrates, and coating hardness.
• Adhesive & Sealant Formulations: Enhances bonding strength and durability, particularly for metal-polymer and glass-polymer interfaces.
• Dispersing Agent for Pigments & Fillers: Improves the stabilization and compatibility of inorganic particles in polymer matrices, preventing agglomeration.
• Dental & Biomedical Materials: Used in the synthesis of resin composites and bone cements to promote adhesion and mechanical integration.
• Surface Modification of Nanoparticles: Functionalizes the surface of oxides (e.g., silica, titania) to facilitate their incorporation into organic polymers.
• Textile & Fiber Treatment: Imparts durable hydrophilic or specific functional properties to synthetic fibers.
• Water Treatment Polymers: Acts as a building block for scale inhibition or dispersant polymers in industrial water systems.
• Specialty Monomer for Copolymerization: Incorporated into acrylic or vinyl polymer chains to introduce phosphate functionality for flame retardancy or corrosion inhibition.
