| titleOfInvention | Catalyst component, catalyst system and prepolymerized catalyst for olefin polymerization, use thereof and olefin polymerization process |
| abstract | The invention belongs to the field of olefin polymerization catalysts, and provides a catalyst component for olefin polymerization, a catalyst system, a pre-polymerization catalyst, application of the pre-polymerization catalyst and an olefin polymerization method. The catalyst component comprises magnesium, titanium, halogen and a compound shown as a formula (I); (I) in R 1 、R 2 、R 3 、R 4 、R 5 And R 6 Each independently selected from hydrogen and substituted or unsubstituted C 1 ‑C 20 Straight chain alkyl, C 3 ‑C 20 Branched alkyl radical, C 3 ‑C 20 A cycloalkyl group. When the catalyst system is used for propylene polymerization, the safety coefficient is higher, the catalyst has better catalytic activity, and the hydrogen regulation sensitivity of the catalyst is good. |
