Abstract
PURPOSE: To provide a catalyst composition for α-olefin polymerization, higher in activity per unit transition metal and carrier which comprises a product, serving as a transition metal component in a zieglar catalyst, obtained from a contact reaction of a liquid Ti halide with a contact reaction product between a specified Mg compound and a specified Ti compound.
CONSTITUTION: An Mg compound (e.g. MgCl2) as shown by the formulaIand a Ti compound (e.g. Ti(O-nC4H9)4) as shown by the formula II are brought into contact with each other at -50W200°C, especially 0W100°C, possibly with the presence of a diluent such as n-heptane, while being stirred. Then, if the resulting product is solid, the solid product is collected and washed as required, possibly with a crushing heat treatment. The product, solid or liquid is brought into contact with a liquid Ti halide (e.g. TiCl4) at -50W200°C, preferably under agitation, to obtain a desired catalyst composition.
