[0231] (3) Preparation method of catalyst

[0232] In the method for producing a catalyst for olefin polymerization according to the present invention, the method of contacting component (A), component (B) and component (C) is not particularly limited, but includes, for example, the following methods:

[0233] (i) a method of contacting component (A) with component (B), and then adding component (C);

[0234] (ii) a method of contacting component (A) with component (C) and then adding component (B);

[0235] (iii) a method of contacting component (B) with component (C), and then adding component (A);

[0236] (iv) A method of simultaneously bringing the components (A), (B) and (C) into contact.

[0237] Furthermore, each component may be used as a mixture of different kinds of components, or may be contacted individually in a different order. This contacting can take place not only during the catalyst preparation but also during the prepolymerization of the olefin or during...

After stirring at room temperature for 1 hour, a solution of bromine (13 mL) in chloroform (40 mL) was added dropwise under cooling in an ice bath, and reacted at room temperature day and night. After the reaction was completed, the reaction solution was poured into 1N hydrochloric acid-ice water, followed by stirring. The organic layer was separated, washed with 1N hydrochloric acid, water and saturated brine, and dried over magnesium sulfate. The solvent was removed by distillation under reduced pressu...

Abstract

The present invention relates to a metallocene complex and a method for manufacturing an olefin polymer. The present invention provides a metallocene complex with which homopolypropylene that has a high melting point can be manufactured in homopolymerization of propylene, and a method for manufacturing olefin polymers using same. The metallocene complex is represented by general formula (I). (Thedefinitions of the substituents in formula (I) are the same as set forth in the Specification).

Description

[0001] This application is a divisional application of the patent application "Metallocene complexes and methods for producing olefin polymers" with an application date of March 17, 2015 and application number 201580015221.9. technical field [0002] The present invention relates to novel metallocene complexes and methods for producing olefin polymers. More specifically, the present invention relates to novel metallocene complexes introducing substituents at specific positions, which can produce polypropylene with a high melting point, and can provide high ethylene uptake efficiency (uptakeefficiency) in the copolymerization of propylene and ethylene, And high activity production of ethylene-propylene copolymer rubber components, and also relates to the production method of olefin polymer. Background technique [0003] Crystalline polypropylene is widely used in various molding fields because of its excellent mechanical properties and chemical resistance. However, a homopol...
