| titleOfInvention | Solid catalyst component for olefins polymerization, method for producing solid catalyst component for olefins polymerization, catalyst for olefins polymerization and method for producing olefins polymer |
| abstract | PROBLEM TO BE SOLVED: To produce a propylene homopolymer having a low melting point of less than 160 ° C. and a high degree of stereoregularity and excellent in melt tension under high polymerization activity without coexistence of α-olefins other than ethylene such as propylene. The present invention relates to a solid catalyst component for polymerizing olefins. A first step in which a magnesium compound, a titanium halogen compound, and a first internal electron donor compound are brought into contact and reacted, and then washed. Of the second internal electron donor compound in an amount of 0.001 to 0.1 mol per mol of magnesium atom contained in the magnesium compound, in the presence of a hydrocarbon solvent, A second step of removing the solvent, a third step of washing one or more times with an organic solvent containing more than 5% by volume and not more than 50% by volume of a titanium halogen compound, and Sequentially applying a fourth step of cleaning one or more times with an organic solvent containing no halogen compound are obtained, olefin polymerization solid catalyst component. 【Selection chart】 None |
