2-Ethylhexyl acrylate, identified by CAS number 103-11-7, is a versatile acrylate monomer characterized as a clear, colorless liquid with a distinctive, sharp odor. This hydrophobic ester is widely utilized in the production of homopolymers and copolymers, where it imparts essential properties such as internal plasticization, low-temperature flexibility, and excellent water resistance. Due to its low glass transition temperature, it is a critical building block for materials requiring softness and tackiness.
In industrial handling, 2-ethylhexyl acrylate is typically stabilized with inhibitors like hydroquinone monomethyl ether (MEHQ) to prevent premature polymerization. It is considered a reactive monomer that must be stored in cool, well-ventilated areas away from direct sunlight and heat sources. Its chemical stability and compatibility with other monomers, such as methyl methacrylate and vinyl acetate, make it an indispensable component in high-performance polymer synthesis for various industrial and research applications.
