How Does TiCl4 Work in Ziegler-Natta Polymerization?
In Ziegler-Natta polymerization, titanium tetrachloride acts as a Lewis acid catalyst. It forms active sites on the catalyst surface when combined with an organoaluminum compound, such as triethylaluminum (Al(C2H5)3). These active sites facilitate the polymerization of olefins like ethylene and propylene by coordinating with the monomers and enabling their insertion into the growing polymer chain.
