Problems solved by technology

In addition, the binding ability of different isomers to magnesium compounds and / or titanium compounds is also different, and even if the compound composed of the same isomer is used as an internal electron donor to prepare a catalyst, due to different preparation conditions, it will cause The content of each isomer is different, which affects the performance of the catalyst

[0061] 1. Preparation of the compound

[0062] Synthesis of succinate compound (I): Synthesis was carried out according to the method described in Journal of Polymer Science: Polymer Chemistry Edition. 1980 (18), 1739-1758 (authors are A. Yamada, S. Grossman and O. Vogl).

[0063] The general procedure is as follows.

[0064] (1) Synthesis of succinate compound (I)

[0065] Add freshly steamed 1.2L THF into a 3L flask with stirring, reflux condenser and dripping device, and add 134g (0.99mmol) of anhydrous CuCl under vigorous stirring 2 . When brown CuCl 2 After the powder becomes orange-red crystals, add 64g (0.98mol) of activated zinc powder and a small amount of HgBr 2 , And then add 100g (0.48mol) ethyl 2-bromoisovalerate dropwise, and heat to reflux for 2h after the addition. Let it settle overnight at room temperature.

[0066] Pour out the clear solution, remove THF under reduced pressure on a rotary evaporator, and pour the remaining liquid into a separatory funnel. The solid...

Abstract

The invention aims to provide catalyst components for CH2=CHR olefin polymerization. The catalyst components include magnesium, titanium, halogen and electron donor. The electron donor is at least a succinate compound selected from a below general formula (I) and contains no less than 51.0wt% of a structure with a Fischer projection as a general formula (II).

Description

Technical field [0001] The invention relates to a solid catalyst component containing a succinate compound with a special structure and a preparation method thereof, a catalyst containing the solid catalyst component and the application of the catalyst in olefin polymerization, especially in propylene polymerization , Can obtain polymers with high yield, high isotacticity and wide molecular weight distribution. technical background [0002] It is well known that solid titanium catalyst components with magnesium, titanium, halogen and electron donors as basic components can be used for olefin polymerization, especially in the polymerization of α-olefins with 3 or more carbon atoms. For polymers with high yield and high stereoregularity, the electron donor compound is one of the indispensable components in the catalyst component, and the development of the internal electron donor compound has led to the continuous update of polyolefin catalysts. At present, a large number of elect...
