Functional Monomers

2-Octyl Acrylate

2-Octyl Acrylate, identified by CAS Number 42928-85-8, is a high-performance specialty monomer belonging to the alkyl acrylate family. This clear, colorless liquid is characterized by its branched C8 structure, which imparts unique rheological and physical properties to its resulting polymers. As a low glass transition temperature (Tg) monomer, it is predominantly utilized to provide internal plasticization, enhancing the flexibility and tackiness of copolymer systems. In the global chemical market, 2-Octyl Acrylate serves as a vital building block for advanced acrylic resins, bridging the gap between standard alkyl acrylates and longer-chain specialty monomers. Its chemical nature allows for excellent copolymerization with various vinyl and acrylic monomers, making it a versatile tool for formulators seeking to optimize peel strength, shear resistance, and low-temperature performance. Its emergence as a preferred alternative in high-solids and UV-curable systems highlights its growing importance in environmentally conscious and high-efficiency manufacturing sectors.
