Description

Polyoxy(Methyl-1,2-Ethanediyl), .Alpha.-Methyl-.Omega.-(2-Propenyloxy)- is a reactive polyether derivative, specifically an allyl-terminated poly(propylene glycol) monomethyl ether. This compound is valued for its terminal allyl ether functionality, which provides a reactive site for further chemical modifications, particularly in polymerization and cross-linking reactions. It is primarily utilized by formulators and researchers in the polymer, coatings, and specialty chemical industries seeking to introduce polyether segments with unsaturated end-groups into their products.

Application

• Macromonomer for Copolymer Synthesis: Acts as a reactive macromonomer in the production of graft or comb-like copolymers via free-radical or other polymerization techniques.
• Cross-linking Agent: Used in the formulation of cross-linkable resins and polymers for coatings, adhesives, and elastomers, where the allyl group participates in curing reactions.
• Polymer Modification: Serves as a functional intermediate to introduce hydrophilic polyether chains into hydrophobic polymer backbones, modifying properties like flexibility, solubility, and surface characteristics.
• Surfactant & Dispersion Aid Precursor: The reactive end-group allows for the synthesis of specialized surfactants or dispersion agents with tailored hydrophobic/hydrophilic balance.
• Hydrophilic Segment for UV-Curable Systems: Incorporated into oligomers for UV-curable inks, coatings, and 3D printing resins to enhance flexibility and reduce shrinkage.
• Bioconjugation & Pharmaceutical Intermediate: Potential use in creating PEGylated derivatives or as a building block for drug delivery systems where a polymerizable handle is required.
