AbstractPolymeriztion of linear low density polyethylene ( LLDPE) using a dual functional catalytic system containing different kinds of Metallocene /AlEt3/B(C6F5)(3) as copolymerization catalysts and Ti(On-Bu)(4)/AlEt3 as the ethylene dimerization catalyst was studied. Using the single cocatalyst AlEt3 in the catalytic system,it is easy to overcome the shortcoming of interference between two catalytic metals in a single reactor. Among the four zirconocene systems used, the most active dual functional catalytic system is [ Ti(On-Bu)(4)/AlEt3/Et(Ind)(2)ZrCl2/B(C6F5)(3)], its activity reaches 7.5 x 10(6) gPE/molZr(.)h. The density of obtained LLDPE is 0.89 g/cm(3) and 1-butene insertion rate 11.7 mol%.
