Application areas
Medical research: Due to its good biocompatibility, PEGMEA is widely used in the field of medical research, especially in drug delivery, gene therapy and tissue engineering. It can modify the surface of materials through copolymerization and cross-linking reactions to change its physicochemical properties and biocompatibility.
Material science: In material science, PEGMEA can be used to prepare high-performance polymer materials. By copolymerizing with other monomers, the physical and chemical properties of the polymer can be adjusted, such as mechanical properties, thermal stability and optical properties.

Surface modification: In addition, polyethylene glycol methyl ether acrylate is also used to modify the surface of materials to improve the biocompatibility, anti-fouling properties and lubrication properties of materials. Synthesis method Polyethylene glycol methyl ether acrylate is usually synthesized by esterification or free radical polymerization. In the esterification reaction, polyethylene glycol monomethyl ether (mPEG) reacts with acrylic acid or its derivatives, and a catalyst such as p-toluenesulfonic acid is usually required to increase the reaction rate and yield. Free radical polymerization requires appropriate initiators and reaction conditions.
