Title:
SOLID CATALYST COMPONENT FOR POLYMERIZATION OF ALPHA-OLEFIN AND PRODUCTION OF ALPHA-OLEFIN POLYMER
Document Type and Number:
Japanese Patent JPH08157513
Kind Code:
A
Abstract:
PURPOSE: To produce an α-olefin polymer in such a manner that the formation of an atactic polyolefin is suppressed while the catalyst activity is kept high.
CONSTITUTION: An α-olefin polymer is produced by using an α-olefin polymerization catalyst component obtained by grinding a compound of the general formula: TiCl3.1/3.AlCl3 (titanium trichloride (AA)) and an electron donor ester (ED) in a molar ratio (AA/ED) of 1-5, treating the obtained solid product with an aromatic hydrocarbon or a halohydrocarbon at 50°C or below and a halogenated organoaluminum compound. According to this process, the polymer formed has little residual catalyst, by-products can be prevented from being formed, and the load in the washing step can be lightened.
