The novel catalysts of TiCl₄-acac-Co(acac)₂, TiCl₄-Co(acac)₂ and TiCl₄-acac supported on SiO₂-MgCl₂ carrier(Ti-Co combined catalyst) were prepared. They catalyze polymerimerization of ethylene giving branched polyethylene when Et₂AlCl was used as a cocatalyst. The polymerization products have low melting point, low crystallinity and high degree of branching as evaluated by FTIR, DSC and ¹³C NMR spectrum. The results of ¹³C NMR suggested more than 55.0% of the polyethylene contain long branch chain(n≥6). Experimental results showed that the Ti-Co combined catalyst exhibites an excellent catalytic property for oligomerization and in situ copolymerization of ethylene.
