Abstract

The present invention relates to a process for producing an .alpha.-olefin oligomer by subjecting .alpha.-olefin to oligomerization in a reaction zone in the presence of a reaction solution containing a chromium-based catalyst, which comprises, PA1 continuously conducting said oligomerization of .alpha.-olefin by using said chromium-based catalyst comprising at least a chromium compound (a), a nitrogen-containing compound (b) selected from the group consisting of amines, amides and imides, and an alkyl aluminum compound (c) while maintaining a molar ratio of the .alpha.-olefin oligomer to .alpha.-olefin in the range of 0.05 to 1.00.
