Abstract
The present disclosure discloses a catalyst composition for polymerization of an α-olefin and preparation and use thereof. The catalyst composition comprises boron trifluoride and at least one protic cocatalyst; the protic cocatalyst has a structural formula of X—(CH)—OH, where n is an integer selected from 1 to 10; X is selected from nitro, halogen, cyano, sulfonic acid group, aldehyde group, acyl, carboxyl and amino. The catalyst can be used in production of a poly(α-olefin) synthetic base oil, and is particularly suitable for a low viscosity poly(α-olefin) synthetic base oil with high selectivity of the target product.
