Description

Acrylic Anhydride CAS NO 2051-76-5 is a highly reactive bifunctional monomer and versatile chemical intermediate. This compound is valued for its ability to introduce acrylic functionality and anhydride groups into polymers and fine chemicals, enabling the synthesis of materials with tailored properties. It is essential for manufacturers in the polymer, specialty chemical, and pharmaceutical industries seeking to develop advanced coatings, adhesives, and functional polymers.

Application

• Polymer Modification: Key intermediate for synthesizing acrylic copolymers and resins with enhanced adhesion, cross-linking density, and weather resistance.
• Specialty Coatings & Adhesives: Used to produce high-performance industrial coatings, pressure-sensitive adhesives, and sealants with improved durability.
• Pharmaceutical Intermediates: Serves as a building block in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs.
• Cross-linking Agent: Functions as an effective cross-linker for hydroxyl- or amine-containing polymers, improving thermal and mechanical stability.
• Surface Treatment: Employed in the surface modification of materials to introduce reactive sites for further functionalization.
• Fine Chemical Synthesis: Utilized in organic synthesis to create acrylate esters, amides, and other derivatives.
