Description

1,1'-Azobis(1-Methylethyl) Diacetate is a high-purity, low-temperature azo initiator widely used in free-radical polymerization processes. Its primary value lies in its ability to efficiently generate free radicals at moderate temperatures, enabling controlled polymer synthesis with specific molecular weights and architectures. This compound is essential for manufacturers in the polymer and specialty chemical industries, particularly for producing acrylic resins, styrenic polymers, and other high-performance materials.

Application

• Polymer Synthesis: A key initiator for the free-radical polymerization of monomers like methyl methacrylate (MMA), styrene, acrylonitrile, and vinyl acetate.
• Acrylic Resin Production: Used in the manufacture of clear acrylic sheets, molding powders, and coatings that require excellent optical clarity and weatherability.
• Adhesive & Sealant Formulation: Serves as a curing agent in the production of pressure-sensitive adhesives (PSAs) and anaerobic sealants.
• Specialty Polymer Manufacturing: Facilitates the synthesis of block copolymers, graft copolymers, and other advanced polymeric materials with tailored properties.
• Cross-linking Agent: Employed to create cross-linked polymer networks for enhanced thermal and mechanical stability in elastomers and plastics.
• Organic Synthesis Intermediate: Acts as a source of free radicals in various organic transformations and synthetic pathways.

Quality Control

Our 1,1'-Azobis(1-Methylethyl) Diacetate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure it meets the high-purity standards required for sensitive polymerization applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee batch-to-batch consistency and performance reliability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at temperatures between 15-25°C (59-77°F). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, the container should be opaque or stored in darkness. Isolate from incompatible materials such as strong oxidizing agents and reducing agents.
