Abstract

The present invention relates to a catalyst composition for oligomerization of ethylene, comprising a chromium compound; a ligand of the general structure R1R2P—N(R3)—P(R4)—N(R5)—H, wherein R1, R2, R3, R4 and R5 are independently selected from halogen, amino, trimethylsilyl, C1-C10-alkyl, aryl and substituted aryl; a modifier containing organic or inorganic halide; and an activator or co-catalyst; and a process for oligomerization utilizing that catalyst.
