Description

Rac-Ethylenebis(1-Indenyl)Dimethylzirconium is a highly active, well-defined metallocene catalyst precursor essential for advanced polyolefin synthesis. This compound matters because it enables precise control over polymer microstructure, including tacticity and molecular weight distribution, which is critical for developing high-performance materials. It is primarily needed by R&D chemists and process engineers in the petrochemical and polymer industries for the production of specialty polyethylenes and polypropylenes with tailored properties.

Application

• As a key single-site catalyst precursor for the homopolymerization and copolymerization of ethylene and propylene.
• In the development of high-performance polyolefin elastomers (POE) and plastomers with specific comonomer incorporation.
• For research into stereospecific polymerization to produce isotactic or syndiotactic polypropylene.
• In catalyst screening and discovery programs aimed at creating polymers with novel thermal and mechanical properties.
• As a model compound in organometallic chemistry and catalysis studies.
• For the production of high-clarity film grades and impact-resistant copolymer resins.

Quality Control

Our Rac-Ethylenebis(1-Indenyl)Dimethylzirconium is manufactured and handled under strict inert atmosphere conditions to ensure batch-to-batch consistency and catalytic activity. Each lot undergoes rigorous quality testing, including NMR and elemental analysis, to confirm identity, purity, and absence of deleterious impurities. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every 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 2-8°C to maintain stability and prevent decomposition. Due to its highly moisture-sensitive and pyrophoric nature, the material must be handled exclusively in a glovebox or using rigorous Schlenk-line techniques.
