Abstract
Abstract A catalyst composition is manufactured by admixing a hydrocarbyl aluminum halide with a nickel compound of the formula (R 1 COO) (R 2 COO) Ni, wherein R 1 is hydrocarbyl of at least 5 carbon atoms and R 2 is haloalkyl of 1-3 carbon atoms. Olefins such as ethylene, propylene and butenes can be oligomerized, for example, dimerized and trimerized, with the above catalyst composition.
