4-Acryloyloxybenzophenone丨CAS 22535-49-5

4-Acryloyloxybenzophenone is an important functional monomer and photoreactive compound used extensively in polymer chemistry, coatings, and advanced materials manufacturing. It acts as a UV-curable crosslinking agent and photosensitizer in the production of photoresists, adhesives, printing inks, and coatings. The compound's acrylate group allows it to copolymerize with acrylic, vinyl, or styrenic monomers, forming polymers with enhanced mechanical and optical properties. Additionally, the benzophenone moiety provides strong UV absorption, making it a valuable component in photoinitiator systems and UV-protective coatings. In advanced materials research, it is utilized in the synthesis of photopolymers, light-sensitive films, and surface-modified materials that respond to UV irradiation.

The compound offers significant advantages due to its dual functionality-combining an acryloyloxy group for polymerization with a benzophenone group for photoreactivity. This structure enables efficient UV crosslinking, leading to polymers with excellent adhesion, hardness, and durability. Its strong UV absorption also imparts photo-stability and protective qualities, extending product life in outdoor and high-intensity light applications. Furthermore, 4-acryloyloxybenzophenone provides good solubility in organic solvents and compatibility with a wide range of monomers and oligomers, allowing versatile formulation design. The compound enhances surface modification capabilities, enabling precise control over polymer structure and performance characteristics in high-performance materials.
