Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-Acetyl-.Omega.-(2-Propenyloxy)- is a specialized reactive polyether derivative, functioning as a macromonomer or polymerizable surfactant. Its core value lies in its unique bifunctional structure, combining a poly(ethylene glycol) backbone with terminal acetyl and allyl ether groups, enabling precise chemical modifications and cross-linking in advanced polymer systems. This compound is essential for industrial chemists and formulators in sectors like specialty coatings, adhesives, and advanced material science, where controlled polymerization and surface activity are required.

Application

• Reactive Macromonomer for the synthesis of graft copolymers and functionalized polymeric networks.
• Cross-linking Agent in UV-curable resins, inks, and coatings to enhance film properties and durability.
• Polymerizable Surfactant (Surfmer) for emulsion and dispersion polymerization, leading to self-stabilizing latex particles.
• Hydrophilic Modifier for imparting water solubility or dispersibility to hydrophobic polymer backbones.
• Precursor for Functional PEGs, used to create polyethylene glycol derivatives with tailored end-group chemistry for bioconjugation or drug delivery systems.
• Additive for Adhesives & Sealants to modify rheology and improve adhesion to various substrates.
