Title:
SILANE COMPOUND, CATALYST COMPOSITION, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/124896
Kind Code:
A1
Abstract:
The present invention provides a silane compound, a catalyst composition, a preparation method therefor and an application thereof. The silane compound has a structure as shown in the following general formula (I), wherein R1 and R2 are the same or different; R1 and R2 are each independently selected from hydrogen atoms, halogen, substituted or unsubstituted alkyl, cycloalkyl, aryl, aralkyl, alkylaryl, and a heteroatom-containing ring; and R3, R4, and R5 are each independently selected from linear or branched alkyl of C1-C8 and linear or branched alkoxy of C1-C8. When the silane compound of the present invention is applied to an olefin polymerization reaction as an external electron donor of the catalyst composition, a catalytic system can have good hydrogen regulation sensitivity, and an olefin polymer having high yield and high isotacticity can be obtained.
