Embodiment 1

[0052] 1. Preparation of solid catalyst

[0053] Add 112ml of toluene and 15g of spherical diethoxymagnesium (average particle size is 20μm, particle distribution index 0.86, apparent density 0.35g / cc), then 20 ml of titanium tetrachloride diluted in 30 ml of toluene was further added thereto, and allowed to react for 1 hour while maintaining the temperature at 10°C. Then, 3.6 g of diisobutyl phthalate and 1.4 g of methyl 4-methoxybutyrate were added thereto while raising the reactor temperature to 100°C. After maintaining the temperature at 100° C. for 2 hours and then lowering to 90° C., stirring was stopped, the supernatant was removed and the resulting product was washed once with an additional 200 ml of toluene. Then 120 ml of toluene and 20 ml of titanium tetrachloride were added thereto, and the temperature was raised to 100°C and maintained for 2 hours, and this process was repeated once. After completion of the aging process, the slurry mixture was washed twice wit...

Embodiment 2

[0068] According to the preparation method of the solid catalyst of Example 1-1, prepare the catalyst, the difference is to add 3.3g diisobutyl phthalate and 2.1g 4-ethoxy ethyl butyrate instead of diisophthalate Mixture of butyl esters and methyl 4-methoxybutyrate. The titanium content in the solid catalyst component was 2.1 wt%. Then, by the same method as in Example 1, polypropylene polymerization and propylene-based copolymerization were carried out, and Table 1 shows the results thereof.

Embodiment 3

[0070] According to the preparation method of the solid catalyst of embodiment 1-1, prepare catalyst, difference is to use the mixture of 4.2g diisobutyl phthalate and 2.8g 5-methoxyvalerate methyl ester to replace phthalic acid Mixture of diisobutyl ester and methyl 4-methoxybutyrate. The titanium content in the solid catalyst component was 2.3 wt%. Then, by the same method as in Example 1, polypropylene polymerization and propylene-based copolymerization were carried out, and Table 1 shows the results thereof.

Abstract

The present disclosure relates to a solid catalyst for propylene polymerization and a process for manufacture of a propylene polymer or copolymer using the solid catalyst, and provides a solid catalyst including carriers produced via a reaction between dialkoxy magnesium and metal halide, titanium halide, an organic electron donor, etc. and a process of manufacture of a propylene-based block copolymer via copolymerization of propylene-alpha-olefin using the solid catalyst. Particularly, internal electron donors including an ester group and an alkoxy group are used as two kinds of organic electron donors used in the present disclosure, and, thus, a block copolymer having high activity and excellent stereoregularity and a high rubber content via copolymerization with alpha-olefin can be produced using a solid catalyst system suggested in the present disclosure.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from Korean Patent Application No. 10-2016-0164086 filed with the Korean Intellectual Property Office on December 5, 2016, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The disclosure of the present invention relates to a solid catalyst comprising a support produced by a reaction between dialkoxymagnesium and a metal halide, a titanium halide, an organic electron donor, etc., and a method for preparing polypropylene using the same. If the Ziegler-Natta catalyst containing this solid catalyst system is used to prepare propylene polymers, propylene resins with high activity, excellent tacticity and high hydrogen reactivity can be produced, and it can also be used with α-olefins Copolymerization produces block copolymers with high rubber content. Background technique [0004] Polypropylene is widely used in real life...
