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

## Abstract Ethylene/1βhexene copolymerization was carried out with polystyreneβsupported metallocene catalyst. It was found that the kinetic of the copolymerization was strongly influenced by the steric hindrance of carrier. The influences of 1βhexene concentration in the feed on catalyst producti
MgCl 2 for use as a catalyst support was prepared by dissolution in methanol and recrystallization in n-decane, followed by vacuum-drying at 2,000 rpm. The prepared support was modified by treatment with alkylaluminum compounds. The activity profile of ethylene over the supported catalysts persisted
Full Paper: Copolymerization of ethylene and 1-hexene was carried out with different catalysts: homogeneous Et[Ind] 2 ZrCl 2 , Cp 2 HfCl 2 and [(C 5 Me 4 )SiMe 2 N(tert-Bu)]TiCl 2 , the corresponding in-situ supported metallocenes, and combined in-situ supported metallocene catalysts (mixtures of Et
