Embodiment 1-27

[0049] Under anhydrous and oxygen-free conditions, add TiCl 4 100ml and toluene 60ml, cool down to -20°C, add 10.0gMgCl 2 ·2.8CH 3 CH 2 OH spherical carrier (prepared according to the method of USP4399054). Rise to 0°C within 1 hour, continue to raise the temperature to 20°C within 2 hours, continue to raise the temperature to 40°C within 1 hour, add 7.4mmol of the corresponding succinate compound in Table 1 (prepared by the aforementioned method) , the temperature was raised to 100°C in 1 hour, maintained for 2 hours, and the filtrate was drained. Add TiCl 4 100ml, raised to 120°C for 1 hour, maintained for 2 hours, and drained the filtrate. Add 60 ml of anhydrous hexane, wash 5 times in a boiling state, then add 60 ml of anhydrous hexane, wash 3 times at normal temperature, and finally vacuum-dry the obtained catalytic component.

Abstract

The invention relates to an olefinic-polymerized catalytic composition, which adopts at least one succinate in a general formula (I) as an internal electron donor. The catalytic composition is used for olefin, and can obtain a polymer with quite high stereospecificity particularly when propylene is copolymerized. The invention also discloses a catalyst containing the catalytic composition.

Description

technical field [0001] The invention relates to an olefin polymerization catalyst component and its catalyst, in particular to a propylene polymerization catalyst component and its catalyst. Background technique [0002] It is well known that solid titanium catalyst components based on magnesium, titanium, halogen and electron donors can be used for CH 2 =CHR Polymerization of olefins, especially in the polymerization of α-olefins with 3 carbon atoms or more, can give polymers with higher yield and higher stereoregularity. Among them, the electron donor is one of the essential components in the catalyst components, and with the development of the electron donor compound, the polyolefin catalyst is constantly updated. [0003] Earlier, a large number of electron donor compounds were reported in the literature, such as polycarboxylic acids, monobasic or polycarboxylic acid esters, acid anhydrides, ketones, monoethers or polyethers, alcohols, amines, etc. and their derivatives...
