Description

Bis(Dodecylcyclopentadienyl)Zirconium(IV) Dichloride is a highly versatile metallocene catalyst precursor, specifically a zirconocene dichloride derivative with long-chain alkyl substituents. This compound is engineered to provide superior solubility in non-polar media and enhanced thermal stability, making it a critical component for advanced polymerization processes. It is primarily sought after by R&D chemists and process engineers in the petrochemical and specialty polymer industries for developing novel polyolefin materials with tailored properties.

Application

• Catalyst Component for Polyolefin Production: Serves as a key precursor for single-site catalysts (e.g., after activation with methylaluminoxane) used in the synthesis of polyethylene (PE) and polypropylene (PP).
• Advanced Material Synthesis: Enables the copolymerization of ethylene with α-olefins (like 1-hexene, 1-octene) to produce linear low-density polyethylene (LLDPE) and elastomers with precise molecular architectures.
• Specialty Polymer Research: Used in R&D laboratories for exploring new polymer structures, including syndiotactic polystyrene and cycloolefin copolymers (COC).
• Functionalized Polyolefins: Facilitates the development of polymers with specific end-group functionalities for subsequent chemical modification.
• Catalyst Screening & Optimization: A standard reagent for testing and optimizing new metallocene catalyst systems in both academic and industrial settings.

Quality Control

Our production of Bis(Dodecylcyclopentadienyl)Zirconium(IV) Dichloride adheres to stringent quality protocols to ensure batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analysis, including NMR spectroscopy and elemental analysis, to verify identity and purity. Certificates of Analysis (COA) detailing all test results are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at a controlled room temperature (15-25°C/59-77°F) in a cool, dry, and well-ventilated area. Due to its hygroscopic and oxygen-sensitive nature, the container must be purged with inert gas before and after each material withdrawal to prevent degradation.
