Abstract
PURPOSE: To produce the title polyolefin having a low fine particle content, a suitable mean particle diameter and a high bulk density in high yields, by using a catalyst comprising a specified solid catalyst component, a specified promotor and an electron-donating compound.
CONSTITUTION: A 3C or higher α-olefin is polymerized by using a catalyst system comprising a solid catalyst component (A) obtained by reacting a homogeneous solution containing at least one compound selected from a mixture of metallic magnesium with a hydroxylated organic compound and an organic oxygen compound of Mg, an electron-donating compound and an organic oxygen compound of Ti with at least one aluminum halide compound and reacting the obtained solid product with a surfactant, an an electron-donating compound and a titanium halide compound and at least one organoaluminum compound (B) and an electron-donating compound (C). A highly streoregular polyolefin of a low fine particle content, a suitable mean particle diameter and a high bulk density can be obtained.
