The effect of different catalyst support treatments in the 1-hexene/ethylene copolymerization with supported metallocene catalysts was investigated through the analysis of molecular weight and chemical composition distributions by means of high temperature gel permeation chromatography (GPC) and cry
MgCl 2 /THF/TiCl 4 (TT-0) were thermally pretreated at 80ΠC for 5 min (TT-1) and 60 min (TT-2), and at 108ΠC 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
