Abstract
A process for preparing a linear .alpha.-olefin having from 4 to 20 carbon atoms is disclosed which comprises polymerizing ethylene or gas containing ethylene in the presence of a catalyst consisting of a zirconium halide, an organoaluminium compound and a Lewis base, and adding a catalyst deactivating agent to the resulting reaction mixture, wherein said Lewis base is at least one member selected from the group consisting of thioethers, alkyl disulfides, thiophenes, thiourea, sulfides, phosphines and primary amines. Use of the catalyst enables preparation of linear .alpha.-olefins of a high purity and reduction in the amount of by-produced wax.
