Definitions
- the present invention relates to a method for producing a catalyst used to polymerize polyolefin, and more particularly to a method for producing a Ziegler-Natta type catalyst for polyolefin polymerization.
- the catalyst for polyolefin polymerization can be classified into a Ziegler-Natta type catalyst, a chromium type catalyst and a metallocene catalyst according to the type of the central metal used. These catalysts are selectively used according to each manufacturing process and application because of different catalyst activity, molecular weight distribution characteristics of polymers and reaction characteristics for comonomers.
- Ziegler-Natta-based catalysts are the most used among the catalysts, and most of them are manufactured in a magnesium chloride supported type.
- These magnesium chloride-supported Ziegler-Natta catalysts generally consist of solid catalyst components consisting of magnesium, titanium, halogens and electron-donating organic compounds, and are highly active because they are applied to various commercial processes such as slurry polymerization, bulk polymerization and gas phase polymerization. And not only basic physical properties such as stereoregularity, but also appropriate particle shape and size, uniform particle size distribution, high apparent density, and the like.
- the carrier used in the preparation of the catalyst is conventionally prepared by using a recrystallization / reprecipitation method, a spray drying method and a method using a chemical reaction.
- the recrystallization / reprecipitation method and spray drying method are most used to manufacture the magnesium chloride carrier, but the catalyst produced by using the carrier prepared by such a method is relatively low in activity, so that the catalyst residue is somewhat present in the polymerization product. It has some limitations that are not suitable for the development of future-oriented eco-friendly materials.
- the catalyst prepared by using a dialkoxy magnesium obtained by reacting magnesium with alcohol which is one of the methods using a chemical reaction, has a high activity and stereoregularity.
