Description

Dichloro-(R,R)-Ethylenebis-(4,5,6,7-Tetrahydro-1-Indenyl)-Titanium(IV) is a highly specialized, chiral metallocene catalyst essential for stereoselective polymerization processes. This compound matters for its ability to impart precise stereochemical control in the production of advanced polyolefins, enabling the creation of polymers with tailored physical properties and performance characteristics. It is primarily needed by R&D chemists and process engineers in the polymer and advanced materials industries, particularly for developing isotactic polypropylene and other stereoregular polymers.

Application

• As a single-site catalyst for the stereoselective polymerization of propylene to produce isotactic polypropylene (iPP).
• In the co-polymerization of ethylene and higher α-olefins to create linear low-density polyethylene (LLDPE) with controlled comonomer distribution.
• For the R&D and pilot-scale synthesis of novel polyolefin elastomers and plastomers with specific tacticity.
• As a key chiral ligand-metal complex in organometallic chemistry research and catalyst discovery programs.
• In the production of high-performance polymer materials requiring exceptional clarity, strength, and thermal resistance.
• For academic and industrial studies on structure-activity relationships in metallocene catalysis.
