Abstract
PURPOSE: To obtain a specific complex suitable to a catalyst for preparing polyethylene having a very narrow distribution of molecular weight and high bulk density, by depositing the complex from solutions containing ethereal complexes of a titanium trihalide and a magnesium halide in an ether respectively.
CONSTITUTION: A complex of the formula (n is 0.01W0.99; 2<m<3; 1<x<3) is deposited from solutions containing an ethereal complex of a titanium trihalide expressed by the formula TiX3.pY (X is halogen; Y is aliphatic or cyclic ether; p is 2 or 3) 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 resultant complex used in combination with a compound of the formula AlRnX3-n (R is 1W14C saturated hydrocarbon residue; n is 2 or 1.5) exhibits a high catalytic activity, reduces the amount thereof in polymerization of olefins, eliminates the catalyst removing step and is advantageous industrially.
