A diimine metal complex represented by Formula I, a preparation method therefor, and application thereof are provided. The complex is used as a main catalyst in catalysts for olefin polymerization, and can achieve catalytic ethylene polymerization at a high temperature to prepare high molecular weight branched polyethylene.

Diimine metal complex, preparation method therefor, and application thereof

A method for preparing an olefin-olefinic alcohol copolymer and an olefin-olefinic alcohol copolymer prepared by the method are provided. The catalyst used in the method for preparing the olefin-olefinic alcohol copolymer has a diimine metal complex as shown in Formula I.

Method for preparing olefin-polar monomer copolymer

An amino-imine metal complex represented by Formula I, its preparation method and an application thereof are provided. The complex is used as a main catalyst in catalysts for olefin polymerization, and can catalyze the polymerization of ethylene at a relatively high temperature to prepare branched polyethylene having high molecular weight.

Amino-imine metal complex and preparation method therefor and application thereof

A catalyst component for ethylene polymerization, including an inorganic oxide support, and at least one alkyl metal compound, at least one halide, at least one dihydrocarbyl magnesium compound, at least one difunctional compound that reacts with the dihydrocarbyl magnesium compound and at least one titanium compound, wherein the difunctional compound is a mono-, di- or multi-halogenated alcohol or phenol having from 2 to 20 carbon atoms; or a mono-, di- or multi-halogenated acyl halide having from 2 to 20 carbon atoms. Also, a process for preparing the catalyst component and use thereof.

Catalyst component for ethylene polymerization, a process for preparing thereof and catalyst comprising the same

The present invention relates to a silica gel-supported catalyst component suitable for ethylene (co)polymerization, a catalyst therefrom and use of the same. The catalyst component according to the present invention is obtained by supporting the reaction product of a titanium compound, a halide promoter, a magnesium compound and an electron donor on silica gel having a larger specific surface area. When the resultant catalyst is used for ethylene polymerization, especially gas phase fluidized bed polymerization, not only the activity is substantially enhanced, but also the hydrogen response and the copolymerizability of ethylene with other alpha-olefins are improved. The catalyst is especially suitable for the fluidized bed polymerization operated in a condensed state, with high quality LLDPE resins being obtained.
