Definitions
- the present invention relates to a catalyst for polymerizing an olefin polymer and a method for producing an olefin polymer or a styrene polymer, and more particularly to a method for efficiently and inexpensively producing an olefin polymer and a styrene polymer.
- a method has been proposed in which a transition metal compound, an aluminoxane or an organoaluminum compound is used as a catalyst component, and polymerization of olefins is carried out using a catalyst in which these are supported on an inorganic oxide such as silicide or alumina (see, for example, Japanese Patent Application Laid-Open No. H11-157572). Japanese Patent Application Laid-Open No. 6-161086, Japanese Patent Application Laid-Open No. Hei 11-1033, etc.).
- a large amount of aluminoxane is required in order to obtain a sufficient polymerization activity. Therefore, the activity per aluminum is low and not only is uneconomical, but also the produced polymer is not economically efficient. There is a problem that since a large amount of lumidium remains, it is necessary to remove the catalyst residue from the polymer.
- the present invention has been made from the above viewpoint, and is inconvenient to handle by using a silane compound, has poor storage stability, does not use a large amount of highly dangerous methylaluminoxane or trimethylaluminum, and uses a polymerization system. Since the amount of organoaluminum used as a whole can be significantly reduced, a large amount of metal does not remain in the produced polymer, and there is no need for post-treatment of the polymer. It is an object of the present invention to provide a method for producing a styrene-based polymer, and moreover, a styrene-based polymer in which syndiotactic stereocontrol is performed.
