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 propylcyclopentadienyl ligands enhance thermal stability and solubility in nonpolar solvents, making it suitable for solution and slurry polymerization processes. Also employed in research for developing new catalysts with tailored activity and selectivity.
