Poly(ethylene glycol) methyl ether acrylate is widely used in the synthesis of hydrogels, which are applied in drug delivery systems due to their biocompatibility and ability to control the release of therapeutic agents. It is also utilized in the production of contact lenses, where its hydrophilic properties help maintain moisture and comfort for the wearer. In the field of surface coatings, this chemical is employed to create antifouling layers that prevent the adhesion of proteins and cells, making it valuable for medical devices and marine applications. Additionally, it serves as a key component in the development of responsive polymers that can change their properties in response to environmental stimuli, such as temperature or pH, which is useful in smart materials and sensors.
