摘要：
A catalyst for polymerizing .alpha.-olefins composed of a titanium composition formed by heating a co-comminuted mixture of a magnesium halide and a complex of an aluminum halide and a carboxylic acid ester of the formula R.sup.1 COOR.sup.2, with titanium tetra-chloride; and an organic aluminum compound of the formula AlR.sup.3 mH.sup.3 --m; and optionally added thereto at least one component selected from an alkyl aluminum halide of the formula AlR.sup.4 nX.sub.3 --n; a carboxylic acid ester of the formula R.sup.5 COOR.sup.6 ; and its complex formed with an aluminum halide; is disclosed.
