Dodecyl 2-methylacrylate丨CAS 142-90-5

Dodecyl 2-methylacrylate is a long-chain alkyl ester of 2-methylacrylic acid widely used in polymer chemistry and material science. It is primarily employed as a monomer in the synthesis of acrylic copolymers, resins, and coatings, where its long alkyl chain imparts hydrophobicity, flexibility, and adhesion properties. These polymers find applications in paints, varnishes, adhesives, sealants, and surface coatings that require enhanced water resistance, durability, and mechanical performance. Additionally, dodecyl 2-methylacrylate is used in the formulation of specialty polymers for textiles, plastics, and emulsions, where it contributes to improved film formation, gloss, and chemical resistance. Its reactivity in free radical polymerization makes it a versatile building block for custom-designed polymeric materials.

The benefits of dodecyl 2-methylacrylate are closely related to its long alkyl chain and reactive acrylate group. The long hydrophobic chain enhances water resistance, flexibility, and adhesion in polymer formulations, making it ideal for coatings and adhesives. Its acrylate functionality allows rapid and efficient polymerization under controlled conditions, enabling high-performance copolymers with tunable mechanical and chemical properties. Incorporation of dodecyl 2-methylacrylate into polymers improves durability, chemical stability, and surface smoothness of end products. Additionally, it supports industrial efficiency by enabling consistent polymerization behavior and compatibility with a wide range of monomers, resins, and additives. These benefits make it a valuable monomer for advanced materials requiring both functional performance and long-term reliability.
