Description

Triisobutyldialuminoxane is a highly reactive organoaluminum compound primarily used as a co-catalyst and activator in polyolefin polymerization processes. Its core value lies in its ability to significantly enhance catalyst performance and control polymer microstructure, which is critical for producing high-performance materials. This chemical is essential for R&D and manufacturing in the petrochemical, specialty polymer, and advanced materials sectors.

Application

• Ziegler-Natta Catalyst Co-catalyst: A key component for activating titanium and vanadium-based catalysts in the production of polyethylene and polypropylene.
• Metallocene Catalyst Activation: Serves as an efficient activator/alkylating agent for metallocene catalysts used in the synthesis of precisely controlled polyolefins.
• Olefin Polymerization Research: Used in laboratory-scale development of new polymerization systems and novel polymer architectures.
• Specialty Elastomer Production: Employed in the synthesis of ethylene-propylene rubbers (EPR) and ethylene-propylene-diene monomer (EPDM) rubbers.
• Fine Chemical Synthesis: Acts as a selective alkylating or reducing agent in organic synthesis for pharmaceutical and agrochemical intermediates.
• Material Science: Utilized in the surface modification of inorganic fillers and the preparation of alumoxane precursors for ceramic materials.

Quality Control

Our Triisobutyldialuminoxane is manufactured under stringent process controls to ensure batch-to-batch consistency and high reactivity. Quality is verified through analytical methods including NMR spectroscopy and titration to confirm aluminum content and alkyl group composition. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles 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) at room temperature (15-25°C) in a cool, dry, well-ventilated area dedicated to pyrophoric/organometallic reagents. Due to its moisture-sensitive and easily oxidized nature, containers must be kept sealed and handled using air-free techniques.
