| titleOfInvention | Polyolefin production method |
| abstract | (57) [Problem] To produce a high-quality polyolefin with low Ti residue and high activity, and to greatly improve powder characteristics. As the transition metal compound (A), (i) at least one member selected from magnesium metal and a hydroxylated organic compound, or at least one member selected from an oxygen-containing organic compound of magnesium, and (ii) at least one member. A homogeneous solution containing at least one oxygen-containing organic compound of titanium and (iii) at least one oxygen-containing organic compound, and (iv) a molar ratio of aluminum atoms to magnesium atoms of the homogeneous solution is 0. In the solid particles obtained by reacting at least one or more halogenated organoaluminum compounds in an amount of 5 to 2.0, (v) the molar ratio of aluminum atoms to magnesium atoms is 1.0. A solid complex obtained by reacting at least one halogenated organoaluminum compound in an amount of ~ 20 is used, and at least one selected from organoaluminum compounds is used as the organometallic compound (B). Polyolefins are produced in the presence of a catalyst. |
