Functional Monomers

Lauryl Methacrylate 1214F (LMA 1214F)

Lauryl Methacrylate 1214F (LMA 1214F), identified by CAS Number 142-90-5, is a high-performance specialty monomer based on a blend of C12 and C14 fatty alcohols. As a long-chain alkyl methacrylate, it plays a critical role in the synthesis of polymers requiring a balance of flexibility and hydrophobicity. This clear, low-viscosity liquid acts as a versatile building block, primarily utilized to lower the glass transition temperature (Tg) of acrylic copolymers. Its unique long-chain structure imparts excellent oil solubility and water resistance to finished products, making it indispensable in the lubricant and coating industries. LMA 1214F is valued for its low volatility and high reactivity, facilitating efficient polymerization processes. By incorporating this monomer, formulators can achieve superior internal plasticization, eliminating the need for external additives. In the global chemical market, LMA 1214F stands out as a reliable intermediate for creating advanced materials that demand durability, chemical resistance, and enhanced adhesion to non-polar substrates.
