Embodiment 1

[0134] (1) Preparation of alkoxy-containing magnesium compounds

[0135] In a three-neck flask with an internal volume of 0.5 liters and a stirrer replaced by nitrogen, put 122 g (2.64 g atoms) of ethanol, 0.9 g (7.1 mg atoms) of iodine and 8 g (0.33 g atoms) of magnesium metal after dehydration. atom), stirred at 78°C (350rpm) to react until no hydrogen gas is generated in the system, and an alkoxy-containing magnesium compound (diethoxymagnesium) was obtained.

[0136] (2) Preparation of solid catalyst components

[0137] After replacing the three-neck flask with a stirrer with an inner volume of 0.5 liters with nitrogen, put in 80 milliliters of dehydrated octane and 16 g (0.140 moles) of diethoxymagnesium prepared in the aforementioned (1) as a carrier. Heating to 40°C, adding 2.4 ml of silicon tetrachloride and stirring for 20 minutes, then adding 2-isobutyl-2-isopropyl-1,3-dimethoxypropane as an internal donor (electron-donating compound) (IPIBMP) 2.9 ml. The temperat...

Embodiment 2

[0142] Except changing 2-isobutyl-2-isopropyl-1,3-dimethoxypropane (2.9 ml) in Example 1(2) to 9,9-bis(methoxymethyl)fluorene Except for (FLUMP) (3.5 ml), a solid catalyst component was prepared in the same manner as in Example 1 (2) and (3), and propylene polymerization was carried out. The results are shown in Table 1.

Embodiment 3

[0144] Except using the diethoxymagnesium prepared in the iodine dosage of 0.27g and the reaction temperature of 40°C in Example 1 (2), the same operation was performed as in Example 1 (2) and (3) to prepare the solid catalyst component and carry out propylene polymerization. The results are shown in Table 1.

Abstract

A solid catalyst component for olefin polymerization, which is obtained by reacting the following compounds (a), (b) and (d), or the following compounds (a), (b), (c) and (d), (a) a halogen-containing titanium compound, (b) an alkoxylated magnesium compound, (c) a halogen-containing silicon compound, (d) electron-donating compound(s) represented by the following general formula (I) and / or general formula (II), wherein n is an integer of 2 to 10, each of R<1> to R<8> is a substituent having at least one element selected from carbon, hydrogen, oxygen, halogen, nitrogen, sulfur, phosphorus, boron or silicon, any substituents of R<1> to R<8> may together form a ring other than a benzene ring, wherein each of R<9> to R<12> is independently a linear, branched or cyclic alkyl group, or an arylalkyl group, having 1 to 20 carbon atoms, provided that the total sum of carbon atoms of R<9> and R<10> is 3 to 40.

Description

technical field [0001] The present invention relates to a solid catalyst component for olefin polymerization for producing an α-olefin homopolymer or copolymer, a catalyst for olefin polymerization, and a method for producing an olefin polymer. Background technique [0002] Generally, olefin polymers are polymerized using Ziegler-Natta catalysts composed of titanium compounds and organoaluminum compounds. For example, in the manufacture of polypropylene, one of the olefin polymers, a solid catalyst component consisting of titanium, magnesium, chlorine, and an electron-donating compound; an organoaluminum compound as a cocatalyst component; Catalysts of organosilicon compounds with alkoxy groups can produce isotactic polypropylene, but at present, in order to improve the catalyst activity during polymerization, improve the stereotacticity of olefin polymers, and stabilize the production of olefin polymers, attempts are made to powder shape improvement, etc. [0003] For exa...
