Abstract

The invention provides an alpha-diimine compound with alkyloxysilicon and application of a supported metal complex of the alpha-diimine compound with alkyloxysilicon. The alpha-diimine compound with alkyloxysilicon has a structural formula as defined in the specification; and in the formula, R1 and R2 are same or different and are respectively one selected from C6-60 aromatic alkyl groups, R3 and R4 are same or different and are respectively one selected from C1-20 alkyl groups, and n is 3, 4, 5, 6 or 7. The active group alkyloxysilicon on the structure of the alpha-diimine compound enables the alpha-diimine compound to be loaded on the surface of a carrier in a covalent bond connection manner, so a loaded alpha-diimine compound is obtained; the loaded alpha-diimine compound is coordinated with a metallic compound, so the supported metal complex of the alpha-diimine compound is obtained; and the supported metal complex of the alpha-diimine compound is applied in polymerization of alkene. During polymerization of alkene, the supported metal complex has good thermal stability when used as a catalyst, is applicable to reaction temperature of 100 DEG C, still maintains high activity and obviously improves the phenomenon of sticking to a kettle in polymerization.

Description

technical field [0001] The invention relates to the field of catalytic polymerization of olefins, in particular to the application of an α-diimine compound with alkoxy silicon and its supported metal complex in olefin polymerization. Background technique [0002] Among the catalysts for olefin polymerization, the late transition metal catalysts represented by α-diimine nickel and palladium late transition metal complexes have many excellent characteristics: (1) less sensitive to air and moisture; (2) The synthesis is simple and stable; (3) the oxophilicity is relatively weak, and it can catalyze the copolymerization of polar monomers and olefins to prepare functionalized polyolefins; (4) the catalytic activity is high; (5) the ligand structure can be adjusted in a large range, By changing the ligand structure, the thermal stability of the catalyst, the chain structure of the polymer, the molecular weight and its distribution, and the physical properties of the polymer are re...
