Beschreibung
Zusammenfassung:	The present invention relates to a catalyst composition for oligomerization of ethylene, com~ prising 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 select-ed 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. La présente invention porte sur une composition de catalyseur pour l'oligomérisation de l'éthylène, comprenant un composé du chrome; un ligand de la structure générale R1R2P-N(R3)-P(R4)-N(R5)-H, dans laquelle R1, R2, R3, R4 et R5 sont choisis indépendamment parmi halogène, amino, triméthylsilyle, alkyle en C1-C10, aryle et aryle substitué; un agent modifiant contenant un halogénure organique ou inorganique; et un activateur ou co-catalyseur; et un procédé d'oligomérisation utilisant ce catalyseur.
