Bisphenol A ethoxylate dimethacrylate, identified by CAS number 24448-20-2, is a versatile difunctional monomer widely utilized in the synthesis of high-performance polymers. Structurally, it consists of a bisphenol A core extended with ethylene oxide units and capped with methacrylate functional groups. This unique architecture balances the rigidity of the aromatic backbone with the flexibility provided by the ethoxy chains, resulting in a material that exhibits low shrinkage during polymerization and excellent mechanical strength.
In industrial and research settings, this chemical is valued for its low volatility and high refractive index. It typically appears as a clear, viscous liquid and is compatible with a wide range of other monomers and resins. Due to its reactive nature, it is often stabilized with inhibitors to prevent premature polymerization during storage. Proper handling involves standard laboratory safety protocols, as the material can act as a skin and eye irritant. Its ability to form robust cross-linked networks makes it indispensable for applications requiring thermal stability and chemical resistance.
