Poly(ethylene glycol) methyl ether methacrylate is widely used in the field of polymer chemistry and material science due to its unique properties. It is commonly employed as a monomer in the synthesis of hydrogels, which are utilized in biomedical applications such as drug delivery systems, tissue engineering, and wound dressings. Its hydrophilic nature and biocompatibility make it suitable for creating materials that can absorb and retain large amounts of water, enhancing their performance in medical environments. Additionally, it is used in the production of coatings and adhesives, where its ability to improve flexibility and moisture resistance is highly valued. In the cosmetics industry, it serves as a key ingredient in formulations for skin care products, providing hydration and a smooth texture. Its versatility also extends to the development of smart materials and sensors, where it contributes to the responsiveness and functionality of the final product.
