Bimodal PE prepared with combined ir

Bimodal PE prepared with combined iron Ⅱ and nickel Ⅱ olefin polymerization catalysts

Combined iron Ⅱ and nickel Ⅱ olefin polymerization catalysts could produce a kind of PE having the characters of ideal bimodal PE with appropriate conditions and catalysts. In the ethylene homopolymerization with triethylalkylaluminum (AlEt3) as the activator, the prepared bimodal PE contained not only branched PE of high molecular weight, but also linear PE of low molecular weight. And the amounts of both fractions were similar. Ideal bimodal PE resin was prepared in one polymerization reactor.
