The invention relates to a
zirconium tetralylmethoxyl
imine complex, a preparation method thereof, and application thereof in
catalysis olefin homopolymerisation and copolymerization. In the preparation method, tetrahydronaphthol
imine neutral ligand is subjected to
hydrogen exchange treatment with
lithium alkylide to obtain ligand
lithium salt, the ligand
lithium salt and
zirconium halide react to obtain a product, the product is then filtered, concentrated and recrystallized to obtain the target complex finally. In the presence of a
promoter, the
zirconium complex can be used for catalyzingreactions such as
ethylene and propylene homopolymerisation and copolymerization between
ethylene and propylene,
ethylene and 1-
hexene, ethylene and 1-octylene, and ethylene and
norbornene. Accordingto the zirconium Tetralylmethoxyl
imine complex, the preparation method and application thereof, the complex has the advantages that raw materials are easy to obtain, synthesis routes of the complex are simple, yield of products is high, property of the complex is stable, the complex has high catalytic activity and can be used for preparing
polyethylene,
polypropylene, and copolymers of ethylene and propylene, ethylene and 1-
hexene, ethylene and 1-octylene, and ethylene and
norbornene which have high molecular weight and
narrow range of the molecular weight, and can meet requirements of industrial sectors.
