Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-2-(2,6-Dimethylphenoxy)-1-(2,6-Dimethylphenoxy)Methylethyl-.Omega.-Hydroxy- is a specialized non-ionic surfactant and polymer intermediate, identified by CAS NO 136132-73-5. Its unique structure, featuring a polyoxyethylene chain capped with bulky 2,6-dimethylphenoxy groups, provides excellent surface activity and compatibility, making it a valuable functional additive. This chemical is primarily sought by formulators in the polymer, coatings, and specialty chemical industries for its role in modifying rheology, enhancing dispersion, and acting as a stabilizer or emulsifier.

Application

• Polymer Additive: Used as a rheology modifier, processing aid, or internal lubricant in polymer melts and composites.
• Coatings & Inks: Functions as a dispersing agent and flow control additive to improve pigment wetting and film formation.
• Specialty Surfactant: Serves as a non-ionic emulsifier or stabilizer in demanding formulations requiring compatibility with hydrophobic systems.
• Adhesive & Sealant Formulations: Acts as a tackifier modifier or plasticizer to adjust adhesion and cohesion properties.
• Lubricant & Grease Additive: Employed as a thickener or performance additive in synthetic lubricants and industrial greases.
• Chemical Intermediate: Utilized in the synthesis of more complex surfactants, dendrimers, or functional polymers.
