Used as a catalyst precursor in olefin polymerization, particularly in the production of polyethylene and polypropylene. It is effective in Ziegler-Natta and metallocene catalytic systems, offering control over polymer molecular weight and microstructure. Its solubility in nonpolar solvents makes it suitable for solution and slurry-phase polymerization processes. Commonly employed in industrial settings to tailor polymer properties such as density, crystallinity, and mechanical strength.
