Description

Poly[Oxy(Methyl-1,2-Ethanediyl)], α-Butyl-ω-Methoxy- is a polyether glycol derivative, specifically a butyl-terminated polyethylene glycol monomethyl ether. This compound matters as a versatile, non-ionic polymeric building block and surfactant, offering a unique balance of hydrophobic and hydrophilic properties due to its terminal butyl and methoxy groups. It is needed by formulators and researchers in the polymer, coatings, and pharmaceutical industries seeking to modify solubility, rheology, or surface activity.

Application

• As a reactive intermediate or macromonomer in the synthesis of specialized polyurethanes, polyesters, and other copolymers.
• As a non-ionic surfactant or dispersant in industrial formulations, including coatings, inks, and agrochemicals.
• As a phase transfer catalyst or solvent modifier in organic synthesis and chemical reactions.
• As a plasticizer or viscosity modifier for polymers and resins to enhance flexibility and processing.
• In pharmaceutical and cosmetic research for drug delivery systems and as an excipient component.
• As a lubricant base or additive in specialty fluid formulations.
