Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-Methyl-.Omega.-(2-Propenyloxy)- is a reactive polyether macromonomer, a key intermediate in the synthesis of advanced polymers. Its value lies in its terminal allyl ether functionality, which enables copolymerization and cross-linking reactions to modify material properties. This product is essential for industrial chemists and formulators in the coatings, adhesives, sealants, and elastomers (CASE) sectors, as well as for producing specialty surfactants and functional fluids.

Application

• Reactive Diluent & Macromonomer: Used in UV-curable and radiation-curable resin systems for coatings, inks, and adhesives to enhance flexibility and reduce viscosity.
• Cross-linking Agent: Serves as a co-monomer in the production of cross-linked polyurethanes, acrylics, and epoxy resins to improve mechanical strength and chemical resistance.
• Surfactant & Emulsifier Intermediate: A key building block for synthesizing non-ionic surfactants and polymeric emulsifiers used in industrial and institutional cleaning formulations.
• Polymer Modification: Employed to introduce polyether side chains into polymer backbones, imparting hydrophilicity, flexibility, or impact resistance to plastics and elastomers.
• Lubricant & Functional Fluid Additive: Incorporated into synthetic lubricants and hydraulic fluids to modify viscosity and thermal stability.
• Silicon Modification: Used in the synthesis of silicone-polyether copolymers for use as foam stabilizers, release agents, and textile auxiliaries.
