The chemical substance with CAS Registry Number 27274-31-3 is most commonly known as Allyloxy polyethylene glycol (abbreviated as APEG). It is a versatile polyethylene glycol (PEG) derivative widely used in industrial and chemical applications due to its unique structural and reactive properties. APEG has key applications in the following aspects. 1. Concrete Additives: A primary use is in manufacturing polycarboxylate superplasticizers (PCEs), critical additives in modern concrete. When copolymerized with acrylic acid or related monomers, APEG-based PCEs disperse cement particles efficiently, improving concrete workability, reducing water demand, and enhancing strength and durability. 2. Polymer Synthesis: As a reactive monomer, APEG is used to prepare hydrophilic polymers, hydrogels, and copolymers. Its allyl group facilitates cross-linking or grafting, enabling customization of polymer properties (e.g., water solubility, viscosity). 3. Surfactants and Emulsifiers: Its amphiphilic structure (hydrophilic PEG + hydrophobic allyl) makes it useful as a surfactant, emulsifier, or dispersant in industries like textiles, coatings, and cosmetics. 4. Specialty Chemicals: Used in modifying silicones (via grafting), producing fluorocarbon resins, superabsorbent polymers, and unsaturated polyesters, where its reactivity and hydrophilicity add functional value. In summary, CAS 27274-31-3 (APEG) is a vital PEG derivative valued for its reactivity, solubility, and versatility, with major applications in construction (concrete additives), polymer chemistry, and industrial formulations.
