Title:
PHOSPHINE-PHENOL HALF-METALLOCENE COMPLEX, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/078525
Kind Code:
A1
Abstract:
The present invention relates to the technical field of olefin polymerization catalysts, and discloses a phosphine-phenol half-metallocene complex, and a preparation method therefor and the use thereof. The structural formula of the phosphine-phenol half-metallocene complex is as shown in formula (I), where M is selected from group IVB metals; Ar is selected from a substituted or unsubstituted C6-C20 aryl; X is selected from halogen and a C1-C10 hydrocarbyl, and n is 1 or 2; and L1 is selected from a substituted or unsubstituted cyclopentadienyl, a substituted or unsubstituted indenyl, a tetrahydroindenyl, and a substituted or unsubstituted fluorenyl. Under the same metal complex and similar polymerization conditions, when the metal complex of the present invention is used as a main catalyst, a higher polymerization activity is achieved, the obtained polymer has an obviously lower molecular weight distribution than that of a polymer obtained in a comparative example, and also has a better copolymerization performance; in addition, the metal complex of the present invention still maintains a relatively high polymerization activity at a relatively high polymerization temperature.
