| titleOfInvention | Method for producing solid catalyst component for polymerization of olefin, solid catalyst component for polymerization of olefin, catalyst for polymerization of olefin, method for producing catalyst for polymerization of olefin and method for producing polymer ofolefin |
| abstract | A solid catalyst component for polymerization of an olefin having a polymerization activity equivalent to or higher than a solid catalyst component having a phthalic acid ester compound or diether compound as an internal electron-donating compound, and can produce an olefin polymer having excellent bulk density and low content of olefin oligomers. A solid catalyst component for polymerization of an olefin is obtained by: (i) bringing compounds selected from particular phthalic acid ester compounds (A), a magnesium compound and a halogen-containing titanium compound into contact; (ii) bringing the first contact product obtained in step (i) and compounds selected from particular diether compounds (B) into contact, and washing the second contact product; and (iii) obtaining a contact product between the washed second contact product and a halogen-containing titanium compound, washing the contact product, and bringing it into contact with particular phthalic acid ester compounds (A) and a halogen-containing titanium compound. |
