    摘要: This invention provides a process for preparing polyolefins using a new catalyst. According to this invention, .alpha.-olefins can be polymerized or copolymerized to have good stereoregularity and at a high activity by the use of such new catalyst. The new catalyst used in this invention consists of [A] a solid component obtained by contacting (1) a magnesium oxide, (2) an aluminum trihalide, (3) a hydroxy compound represented by the general formula ROH wherein R is an organic radical having 1 to 20 carbon atoms and (4) a titanium halide and/or an addition product of a titanium halide and an aromatic carboxylic acid ester, and [B] an organometallic compound and/or an addition product of an organometallic compound and an aromatic carboxylic acid ester; or it consists of the solid component of the above [A], the organometallic compound and/or the addition product of an organometallic compound and an aromatic carboxylic acid ester of the above [B], and [C] an aromatic carboxylic acid ester. The said catalyst is prepared, in one of the most preferred embodiments thereof, by using the solid component of the above [A] which is obtained by first co-pulverizing the compounds of the above (1),(2) and (3), then washing the co-pulverized product with an aromatic compound, separating the liquid phase to give a solid substance (a) and contacting the latter with the compound and/or the addition product of the above (4).
