Zusammenfassung:	A process for oligomerisation of an olefinic compound for producing an oligomeric product is carried out in the presence of an activated catalyst a non metal oxygen containing additive and optionally a zinc compound. The oligomerisation catalyst is an activated catalyst which is provided by combining a source of chromium a ligating compound and a catalyst activator or combination of catalyst activators. The non metal oxygen containing additive is present in an amount such that the ratio of the molar amount of the non metal oxygen containing additive to the molar amount of chromium in the source of chromium per 10 6g/g Cr productivity is between 0.01 and 400.
