Benzyl Methacrylate (BzMA), ≥95%, is an aromatic methacrylate monomer used in polymer and copolymer synthesis. The benzyl side group contributes rigidity, hydrophobicity, and optical clarity while the methacrylate functionality enables free-radical polymerization with compatible vinyl monomers.
Synonyms: BzMA; Methacrylic Acid Benzyl Ester.
Benzyl Methacrylate is commonly incorporated into acrylic and methacrylic polymer systems to modify physical properties such as glass transition temperature, hardness, refractive index, and chemical resistance. Final polymer properties depend on the comonomers, initiator system, formulation, and processing conditions.
