Title:
METHOD FOR PREPARING HIGH VISCOSITY INDEX POLY-α-OLEFIN
Document Type and Number:
WIPO Patent Application WO/2021/083307
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a high viscosity index poly-α-olefin, comprising: α-olefin is subject to a polymerization reaction in the presence of a metallocene catalyst to obtain a poly-α-olefin, wherein the polymerization reaction is carried out in the absence of a solvent, the metallocene catalyst is formed of, or is formed by interaction between, a metallocene compound and an activator, and the metallocene compound has a structure as represented by formula (I). By the method provided by the present invention, the use of a solvent can be avoided, and a high viscosity index poly-α-olefin can also be obtained.
