ABSTRACT:
Catalyst composition for oligomerizing olefins, obtained by contacting (a) a bivalent nickel compound with (b) a hydrocarbylaluminum compound of the formula AIRCl.sub.2 where R is a monovalent hydrocarbon radical, and (c) a Bronsted acid consisting preferably of a halogenocarboxylic acid of the formula R.sub.1 COOH in which R.sub.1 is a halogenoalkyl radical of the formula C.sub.m H.sub.p X.sub.q, X being halogen, m an integer from 1 to 3, p being zero or an integer and q being an integer, the condition p+q=2m+1 being fulfilled. A preferred Bronsted acid is of the formula R.sub.2 COOH in which R.sub.2 is a halogenomethyl group of the formula CX.sub.n H.sub.3-n, X being halogen and n an integer from 1 to 3.
