Abstract A dual-function long-branch-chain polyethylene catalysis system is composed of primary and secondary catalysts. Said primary catalyst is ethylene eligomerizing catalyst and copolymerizing catalyst. Said secondary one is alkyl aluminoxyane. Its advantages include higher catalytic activity, 2000-3000000 of molecular weight and 5-15% of comonomer mole insertion rate.
