## Abstract A high‐activity Ziegler–Natta catalyst of TiCl~4~‐supported MgCl~2~ (ethoxide type) was prepared. Ethyl benzoate (EB) and polydimethylsiloxane (PDMS) were used as internal donors, while __p__‐methyl toluate (MPT) and triethylaluminum (TEA) were used as the external donor and cocatalyst,
