ABSTRACT OF THE DISCLOSURE A method for the production of a solid titanium trichloride catalyst by the steps of preparing a titanium trichloride composition comprising a solid reduction product obtained by reducing titanium tetrachloride with an organoaluminum compound represented by the formula, R1nA?Y3-n (wherein R1 is a hydrocarbon group having 1 to 18 carbon atoms; Y is a halogen atom or a hydrogen atom; and n is a number satisfying the equation, 1 < n ? 3), or a solid product obtained by thermally treating said solid reduction product at a temperature of not more than 150°C; reacting said titanium trichloride composi- tion in an aromatic hydrocarbon solvent with a mixture consisting of a halogen compound represented by the . . formula, X2 (wherein X is C?, Br, or I), or an inter- halogen compound represented by the formula, XX:a (wherein X and X1 are each C?, Br, or I, and a is 1 or 3), and an ether compound represented by the formula, R2-O-R3 (wherein R2 and R3, which may be the same or different, are each an alkyl group having 1 to 10 carbon atoms); subjecting the resulting reaction mixture to solid-liquid separation; and washing the resulting solid product with an inert hydrocarbon solvent, which method is characterized by using an aliphatic hydrocarbon as a washing medium during at least the first of washing treatments performed subsequently to said solid-liquid separation of said reaction mixture.
