ABSTRACT:
The present invention relates to a process for oligomerization/polymerization of ethylene and/or alpha-olefins, comprising the steps of oligomerizing/polymerizing ethylene and/or alpha-olefins to produce a reaction product which contains undesired reaction by-products, separating the reaction by-product from the reaction product as one or more reaction by-product fractions, and subjecting at least one of the reaction by-product fractions to steam cracking to produce a steam cracking product which comprises ethylene, which may be optionally purified and feed to the oligomerization/polymerization of ethylene and/or alpha olefins step.
