MgCl 2 /THF/TiCl 4 (TT-0) were thermally pretreated at 80ЊC for 5 min (TT-1) and 60 min (TT-2), and at 108ЊC for 5 min (TT-3) and 60 min (TT-4). These thermally pretreated catalysts showed comonomer enhancement effects in the ethylene-1-hexene copolymerization, while TT-0 catalyst did not. Comonomer

Thermally pretreated catalysts were prepared by heating MgCl 2 /THF/ TiCl 4 (TT-0) at 80ЊC for 5 min (TT-1) and 60 min (TT-2), and at 108ЊC for 5 min (TT-3) and 60 min (TT-4). Ethylene-1-hexene copolymers were prepared with these catalysts. The TT-1 catalyst produced more blocky and higher 1-hexene

## 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,
