METALLOCENE COMPOUND, PREPARATION METHOD AND USE

WIPO Patent Application WO/2024/066024

A1

A metallocene compound, a preparation method and a use. The metallocene compound comprises a structure represented by formula a: Ar is selected from substituted or unsubstituted C6-C30 aryl; Cp is selected from substituted or unsubstituted cyclopentadienyl, indenyl, or fluorenyl; X is at least one among halogen, substituted or unsubstituted C1-C30 alkyl, alkoxy, substituted or unsubstituted C2-C30 dialkylamino, alkenyl, or substituted or unsubstituted C6-C30 aryl; and M is a transition metal element. The metallocene compound is not only suitable for catalyzing C6-C30 long straight-chain alpha-olefin raw materials, but is also suitable for catalyzing mixed long-branch chain internal olefin raw materials, and the metallocene compound can, according to requirements, obtain a polymerization product with a target molecular weight.
