Abstract

The invention relates to a supported non-metallocene catalyst and its preparation method and use. The supported non-metallocene catalyst has the characteristics of simple and feasible processes and obvious comonomer effects. A polyolefin product prepared by the supported non-metallocene catalyst is especially suitable as a raw material which can be directly used for preparing chlorinated polyolefin.

Example Embodiment

[0284] Example 1
[0285] Alkoxy magnesium balls use diethoxy magnesium balls (sphericity is 1.42, bulk density is 0.32g/cm 3 , And the average particle size is 420 microns), the contact solvent is n-octane, and the chemical treatment agent is titanium tetrachloride. The structure of non-metallocene ligands is compound of.
[0286] Weigh 5g of diethoxy magnesium spheres and non-metallocene ligand, add n-heptane solvent, stir for 30min at 300rpm and heat to 90 o C to make the system uniformly dispersed, and then add titanium tetrachloride dropwise to the reaction system at a uniform speed. The dropping time is 2 hours. o The reaction was stirred at C for 6 hours, filtered, washed with hexane 3 times, using 60 ml of hexane each time, and dried under vacuum at room temperature to obtain a supported non-metallocene catalyst.
[0287] Among them, the ratio is that the ratio of diethoxy magnesium spheres to n-heptane is 1mol: 1000ml; the molar ratio of diethoxy magnesium spheres to non-metallocene ligands is 1:0.01; diethoxy magnesium spheres and tetrachloride The molar ratio of titanium oxide is 1:2.1.
[0288] The supported non-metallocene catalyst is referred to as CAT-1.

Example Embodiment

[0289] Example 2
[0290] It is basically the same as embodiment 1, but has the following changes:
[0291] Non-metallocene ligand use , The contact solvent is changed to heptane, and the chemical treatment agent is changed to zirconium tetrachloride (TiBr 4 ), the reaction temperature is changed to 85 o C, continue at 85 after dropping o The reaction was stirred at C for 10 hours.
[0292] The ratio of magnesium alkoxide balls to contact solvent is 1mol:1500ml; the molar ratio of magnesium alkoxide balls to non-metallocene ligand is 1:0.015; the molar ratio of magnesium alkoxide balls to chemical treatment agent It is 1:3.
[0293] The supported non-metallocene catalyst is referred to as CAT-2.

Example Embodiment

[0294] Example 3
[0295] It is basically the same as embodiment 1, but has the following changes:
[0296] Alkoxy magnesium balls changed to dipropoxy magnesium balls (Mg(OPr) 2 ) (Sphericity is 1.83, bulk density is 0.40g/cm 3 , And the average particle size is 530 microns), non-metallocene ligands are used , The contact solvent is changed to ethylbenzene, and the reaction temperature is changed to 95 o C, continue at 95 after dropping o The reaction was stirred at C for 4 hours.
[0297] The ratio of magnesium alkoxide balls to contact solvent is 1mol:2000ml; the molar ratio of magnesium alkoxide balls to non-metallocene ligand is 1:0.02; the molar ratio of magnesium alkoxide balls to chemical treatment agent It is 1:5.
[0298] The supported non-metallocene catalyst is referred to as CAT-3.
