Abstract
PURPOSE: To obtain a specific complex suitable to a catalyst for polymerizing olefins having a very narrow distribution of molecular weight and a high bulk density, by depositing the complex from solutions containing ethereal complexes of a titanium tetrahalide and a magnesium halide in an ether respectively.
CONSTITUTION: A complex of the formula (n is 0.01W0.99; 2<m<4; 1<x<3) is deposited from solutions containing an ethereal complex of a titanium tetrahalide expressed by the formula TiX4.pY (X is halogen; Y is aliphatic or cyclic ether; p is 2) and an ethereal complex of a magnesium halide expressed by the formula MgX2.p'Y (1≤p'≤2) in an ether, e.g. THF, respectively. The compound of the formula used with a compound of the formula AlRnX3-n (R is 1W14C saturated hydrocarbon residue; n is 2 or 1.5) exhibits the polymerizing activity of olefins.
EFFECT: A small amount of the catalyst is sufficient, and the catalyst removing step can be eliminated.
