摘要：
A method for oligomerizing an .alpha.-olefin in the presence of a catalyst comprising a specific chromium compound including chromium atom and pyrrolyl group and an alkylaluminum compound, wherein the .alpha.-olefin is contacted to the chromium compound and the alkylaluminum compound without preliminarily contacting the chromium compound to either the .alpha.-olefin or the alkylaluminum compound.
