    摘要: A process for the preparation of a stereospecific .alpha.-olefin polymerization catalyst which comprises (i) forming a solid carrier from an anhydrous magnesium compound and an electron donor compound; (ii) contacting the solid carrier obtained in step (i) with a solution of TiCl.sub.4 in an inert solvent; and (iii) reducing the TiCl.sub.4 with a reducing agent of the formulaAlR.sub.n X.sub.3-nwherein R is an alkyl group having from 1 to 18 carbon atoms, X is a halogen atom, and n is an integer such that 0
