Used as a highly efficient catalyst in stereospecific polymerization of olefins, particularly in the production of isotactic polypropylene. Its chiral ligand structure enables precise control over polymer tacticity, leading to materials with improved mechanical strength, thermal stability, and processability. Commonly employed in gas-phase or slurry-phase polymerization processes when supported on activators like methylaluminoxane (MAO). Plays a key role in industrial polyolefin manufacturing where high stereoregularity is required.
