Embodiment 1-10

[0111] The preparation of embodiment 1-10 solid catalyst component:

[0112] Get the alkoxymagnesium carrier 10g that makes in the preparation example, toluene 50mL, add the electron donor compound shown in Table 1 (comprising electron donor compound I and optional electron donor compound II) and be mixed with suspension; Add 40mL of toluene and 60mL of titanium tetrachloride to the 300mL reaction kettle that has been repeatedly replaced by high-purity nitrogen, then add the prepared suspension into the kettle, raise the temperature to 80°C, and continue to heat up to 115°C after constant temperature for 1 hour. After 2 hours, the liquid (mother liquor) was press-filtered clean. Add a mixed solution of 90 mL of toluene and 60 mL of titanium tetrachloride and raise the temperature to 110° C. and stir for 1 hour (titanium treatment), press filter the liquid (mother liquor), then add a mixed solution of 120 mL of toluene and 30 mL of titanium tetrachloride and raise the temperatu...

Abstract

The invention discloses a catalyst component for olefin polymerization. The catalyst component contains titanium, magnesium, halogen and an internal electron donor compound, wherein the internal electron donor compound comprises an amino ester compound shown as general formula I in the description. A catalyst with excellent combination property can be obtained by adopting a novel internal electrondonor system, satisfactory polymerization yield can be realized when the catalyst is applied to propylene polymerization, hydrogen response of the catalyst is improved, the stereospecificity is higher, and development of polymers with different grades is facilitated.

Description

technical field [0001] The invention relates to a solid catalyst component containing an electron donor compound with a specific structure and a preparation method thereof, the catalyst containing the solid catalyst component and the catalyst in CH 2 = Application in CHR olefin polymerization, where R is hydrogen or C 1 -C 6 The alkyl or aryl group, especially in the application of propylene polymerization. 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-donating compounds are one of the essential components in Ziegler-Natta catalyst components. From the early disclosed monobasic carboxylic acid ester compounds, such as ethyl be...
