According to the present invention there is provided a process for producing an oligomeric product by the oligomerisation of at least one olefi&#x3c0;ic compound, by contacting the at least one olefinic compound with the combination of an oligomerisation catalyst and a catalyst activator. The catalyst activator is a compound which includes at least one halogenated organic group which is bound to one or more binding atoms selected from the group consisting of a group 5A atom and a group 6A atom, which one or more binding atoms are in turn bound to a central atom selected from the group consisting of a group 3A atom, and a group 3B to 7B transition metal atom. The oligomerisation catalyst includes the combination of i) a source of a transition metal; and ii) a ligating compound of the formula (R)mX(Y)X(R)n The invention also relates to a combination of an aligomerisation catalyst and a catalyst activator as set out above and to the use of such a combination in an oligomerisation process.
