| titleOfInvention | Catalyst component for olefin polymerization and catalyst thereof |
| abstract | The invention relates to a catalyst component for olefin polymerization and a catalyst thereof. The catalyst component comprises magnesium, titanium, halogen, an internal electron donor compound and a precipitation aid, wherein the precipitation aid comprises a precipitation aid a shown in a general formula (I); the auxiliary precipitating agent a shown in the general formula (I) comprises optical isomers shown in the general formula (I-a) and/or the general formula (I-b), and the content of the optical isomers shown in the general formula (I-a) and/or the general formula (I-b) is more than 90 wt%. When the catalyst is used for olefin polymerization reaction, the catalyst has higher activity and stereospecific capacity, and the prepared polypropylene has narrower molecular weight distribution, and is particularly suitable for preparing propylene polymers with narrow molecular weight distribution. |
