Embodiment 1

[0114] Take 10 g of the above-mentioned dialkoxymagnesium carrier, 50 mL of toluene, and 0.8 g of compound internal electron donor 1 to prepare a suspension. In a 300mL reaction kettle that has been repeatedly replaced with high-purity nitrogen, add 40mL of toluene and 60mL of titanium tetrachloride, raise the temperature to 65°C, then slowly add the prepared suspension into the kettle, keep the temperature at 65°C for 1 hour, and slowly raise the temperature to 110°C, when the temperature rises to 80°C, add 2.2g of compound internal electron donor 1, keep the temperature at 110°C for 1 hour, press filter to obtain a solid. The obtained solid was washed twice with 150 mL of toluene, and the liquid was removed by pressure filtration. A mixed solution of 90 mL of toluene and 60 mL of titanium tetrachloride was added and stirred at 110° C. for 1 hour, and treated twice in this way. Press filtration, wash the obtained solid once with toluene and 4 times with 150 mL of hexane, pre...

Embodiment 2-12

[0116] The internal electron donors were replaced with 3.0 g each of compound internal electron donors 2-12, and the other steps were the same as in Example 1.

Description

technical field [0001] The invention belongs to the field of catalysts, and in particular relates to a catalyst component for olefin polymerization, a catalyst system and applications thereof. Background technique [0002] A solid titanium catalyst component based on magnesium, titanium, halogen and an electron donor, known in the art as a Ziegler-Natta catalyst, 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. It is well known that electron donor compounds are one of the essential components in Ziegler-Natta catalyst components. From the early disclosed monobasic carboxylic acid ester compounds, such as ethyl benzoate, to the widely used dibasic aromatic carboxylic acid ester compounds, such as di-n-butyl phthalate or diisobutyl phthalate, Then to the recently disclosed 1,3-diethers (CN1020448C), succinates (CN1313869) and 1,3-dio...
