Abstract
PURPOSE: To prepare an excellent catalyst component producing a high proportion of a steroregular polymer, by treating a purplish red product obtained by the reduction of TiCl4 with a mixture of organic Al compounds, with a complexing agent and a 3C or higher chlorinated hydrocarbon.
CONSTITUTION: TiCl4 is reduced with a mixture or a complex compound of a dialkylaluminum monohalide (e.g., diethylaluminum chloride) and a monoalkyaluminum dihalide (e.g., ethylaluminum dichloride). The resulting purplish red reduced solid is treated with a complexing agent (e.g., di-n-butyl ether) and, after separated, it is treated with a 3C or higher chlorinated hydrocarbon (a 3W8C, 2W6Cl one is largely effective, e.g., hexachloropropane), to obtain a catalyst composition for the polymerization of an α-olefin. The catalyst obtained in the method has extremely high polymerization activity and produces a high proportion of a stereoregular polymer and is capable of giving a product composed of uniform particles.
