Used as a catalyst precursor in olefin polymerization, particularly in the production of polyethylene and polypropylene. It is effective in gas-phase and solution-phase polymerization processes due to its high thermal stability and reactivity. When activated with cocatalysts like methylaluminoxane (MAO), it forms highly active zirconocene species that enable control over polymer molecular weight and microstructure. Commonly employed in single-site catalysis for manufacturing plastics with narrow molecular weight distribution and tailored properties. Also utilized in research for developing new metallocene-based catalyst systems for stereospecific polymerizations.
