Document Type and Number:
WIPO Patent Application WO/2024/078528
Kind Code:
A1
Abstract:
A phosphine-phenol transition metal complex, a preparation method therefor, and a use thereof. The structural formula of the phosphine-phenol transition metal complex is shown in formula (I), M being selected from Group IVB metals, Ar being selected from substituted or unsubstituted C6-C20 aryls, X being selected from halogen and C1-C10 hydrocarbons, and n being one or two. The phosphine-phenol transition metal complex is used as a main catalyst of an olefin polymerization catalyst and can achieve high activity in catalyzing olefin polymerization. The obtained polymer has a high molecular weight, a narrow molecular weight distribution, and excellent copolymerization properties.
