Used as a highly effective co-catalyst in olefin polymerization reactions, particularly with metallocene catalysts, to produce polyethylene and polypropylene with controlled molecular weights and narrow polydispersity. Its strong Lewis acidity enhances catalyst activity and stability in non-polar environments. Also employed in cationic polymerization of cyclic ethers and vinyl monomers where high ionic conductivity and thermal stability are required. The ether complex form improves solubility and handling in organic solvents, making it suitable for use in battery electrolytes and advanced materials synthesis.
