Octadecyl Methacrylate (CAS 32360-05-7) is a chemical compound of significant industrial importance, primarily serving as a monomer in the creation of advanced polymers. Its unique molecular structure, combining a reactive methacrylate functional group with a long hydrophobic stearyl tail, dictates its diverse applications in sectors ranging from coatings and adhesives to lubricants and specialty textiles. As a leading manufacturer in China, we delve into the synthesis and properties that make this compound indispensable.

The chemical synthesis of Octadecyl Methacrylate typically involves the esterification of methacrylic acid or methacrylic anhydride with octadecanol (stearyl alcohol). This process yields the target ester, Octadecyl Methacrylate, with the molecular formula C22H42O2. The resulting molecule is characterized by its substantial aliphatic chain, which imparts lipophilic properties and influences the physical characteristics of polymers derived from it. The purity of the octadecanol used directly impacts the final assay of the monomer, which is why our production focuses on achieving a minimum of 99% purity.

One of the most notable properties of Octadecyl Methacrylate is its low glass transition temperature (Tg) when polymerized. This characteristic contributes to the flexibility and elasticity of the resulting polymers, making them suitable for applications where mechanical resilience is crucial, such as in certain types of adhesives and flexible coatings. The long alkyl chain also enhances the hydrophobicity and oil repellency of the polymer matrix, a property exploited in textile and leather treatments, as well as in the formulation of waterproof and oil-resistant agents.

Furthermore, Octadecyl Methacrylate is utilized in the synthesis of lubricant additives, where its long hydrophobic tail can help improve the viscosity index and pour point of base oils. Its ability to form stable polymer chains that can withstand varying temperatures is essential for maintaining lubricant performance under demanding conditions. For businesses looking to buy Octadecyl Methacrylate, understanding these properties is key to optimizing their formulations.
