Description

Tetraisobutyldialuminoxane is a highly reactive organoaluminum compound primarily used as a catalyst component and co-catalyst in polymerization processes. Its value lies in its ability to activate metallocene and other single-site catalysts, enabling precise control over polymer microstructure and properties. This makes it a critical material for manufacturers in the polyolefin industry, particularly for producing specialty polymers, elastomers, and advanced materials with tailored characteristics.

Application

• Primary co-catalyst for activating metallocene catalysts in polyolefin (polyethylene, polypropylene) production.
• Essential component in Ziegler-Natta catalyst systems for the synthesis of polymers and elastomers.
• Used in the production of high-performance, specialty polymers with controlled molecular weight and tacticity.
• Employed as a reagent in organic synthesis for the formation of aluminum-carbon bonds.
• Facilitates the synthesis of fine chemicals and pharmaceutical intermediates.
• Acts as a Lewis acid in various catalytic transformations and material science applications.

Quality Control

Our Tetraisobutyldialuminoxane is manufactured under stringent conditions to ensure batch-to-batch consistency and high reactivity. Quality is verified through a comprehensive suite of analytical techniques including NMR, titration for aluminum content, and impurity profiling. A detailed Certificate of Analysis (COA) documenting purity, assay, and key parameters is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under a dry, inert atmosphere (argon or nitrogen) in a cool, dry, well-ventilated area. Due to its hygroscopic and pyrophoric nature, containers must be kept sealed and handled under inert conditions to prevent contact with moisture and air.
