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-m...

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.

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.

Description

[0001] This application is based on the ongoing research project of "National Eleventh Five-Year Support Program Topics". The project has been highly valued and strongly supported by the Ministry of Science and Technology of the People's Republic of China. Its goal is to form a new generation of polyolefin catalyst technology with independent intellectual property rights, improve the homogeneity of domestic related products, improve the grade of polyolefin varieties in my country, and promote its development. Development in the direction of diversification, serialization, specialization and high performance. technical field [0002] The present invention relates to a non-metallocene catalyst. Specifically, the present invention relates to a supported non-metallocene catalyst, its preparation method and its application in olefin homopolymerization / copolymerization. Background technique [0003] Chlorinated polyethylene (CPE) is a random polymer produced by substitution reacti...
