Decyl methacrylate, identified by CAS 3179-47-3, is a specialized monofunctional monomer belonging to the methacrylate ester family. It is characterized by its long-chain alkyl group, which imparts distinct hydrophobic properties and flexibility to the resulting polymer structures. As a clear, low-volatility liquid, it serves as a critical building block in the synthesis of high-performance acrylic resins and copolymers.
In industrial and research settings, this chemical is valued for its ability to lower the glass transition temperature (Tg) of polymer systems, effectively acting as an internal plasticizer. Its chemical structure allows for efficient free-radical polymerization, making it compatible with various other monomers. Proper handling is essential, as it is typically stabilized with inhibitors to prevent premature polymerization during storage and transport.
