Description

1,2-Ethylenebis(9-Fluorenyl)Zirconium Dichloride is a highly specialized metallocene catalyst precursor, a key component in advanced polyolefin polymerization processes. Its precise molecular structure enables exceptional control over polymer tacticity, molecular weight distribution, and comonomer incorporation, which is critical for developing high-performance materials. This compound is essential for R&D and production teams in the catalyst manufacturing, specialty polymer, and advanced materials sectors seeking to innovate in areas like elastomers and engineering plastics.

Application

• Catalyst Component for Olefin Polymerization: Serves as a single-site catalyst precursor for the production of polypropylene (PP) and polyethylene (PE) with tailored properties.
• Synthesis of Syndiotactic Polymers: Used in the development of syndiotactic polystyrene (sPS) and other stereospecific polymers requiring precise stereochemical control.
• Advanced Material Research: A critical reagent in academic and industrial R&D for exploring new metallocene catalysts and polymerization mechanisms.
• Specialty Elastomer Production: Enables the synthesis of ethylene-propylene-diene monomer (EPDM) rubbers and other polyolefin elastomers (POE) with specific performance characteristics.
• Co-catalyst Systems: Activated with methylaluminoxane (MAO) or other co-catalysts to form the active catalytic species for polymerization reactions.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, this material must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended storage temperature is 2-8°C for long-term stability. The container should be kept tightly sealed in a desiccator when not in use to prevent degradation from atmospheric moisture and oxygen.
