Description

[1,1′-Biphenyl]-4,4′-diyl bis(2-methylacrylate) (CAS No. 13082-48-9) is a high-purity bifunctional monomer with the molecular formula C20H18O4. This compound features a biphenyl core symmetrically functionalized with two 2-methylacrylate groups, making it an excellent crosslinking agent for polymerization reactions. Its rigid biphenyl backbone enhances thermal stability and mechanical strength in polymer matrices, while the methacrylate termini enable radical-initiated copolymerization with other monomers. Ideal for advanced material synthesis, this monomer is suited for photoresists, coatings, adhesives, and specialty polymers requiring high crosslink density. Supplied as a white to off-white crystalline solid with ≥95% purity (HPLC), it is packaged under inert gas to ensure stability and longevity. Store in a cool, dry place away from light and peroxides.
