Abstract
A novel catalytic composition comprises a mixture of lithium halide, a hydrocarbylaluminium halide and at least one compound of a catalytic element, in particular a nickel complex. The invention also concerns a process for the oligomerisation and co-oligomerisation of olefins catalysed by said composition. The catalytic mixture, which is liquid at the start of the reaction, is gradually transformed into a solid which is then readily separated from the reaction products.
