Abstract

PURPOSE: To obtain a polymer in high yields, by polymerizing an α-olefin with the aid of a catalyst comprising a combination of a dialkylaluminum compound and the product obtained from an electron donor, an organic Al compound and TiCl4.
CONSTITUTION: A reaction product is obtained by reacting, in the presence of an aromatic compound, TiCl4 with the reaction product obtained by reacting an electron donor such as methanol with an organic Al compound such as triethylaluminum at a mol ratio of 0.2W8 in a solvent. Then, this product is combined with a dialkylaluminum compound. Next, an α-olefin such as ethylene is reacted with the aid of this combination and then, further, preactivation of the catalyst is performed by addition thereto of the reaction product of a trialkylaluminum and an electron donor such as diphenyl ether. A highly crystalline polymer in the form of well-shaped particles is obtained by polymerizing an α-olefin such as ethylene or propylene in the presence of the above preactivated catalyst.
