Beschreibung
Zusammenfassung:	A catalyst composition including: (a) a chromium compound; (b) a ligand of the general structure(A) R1R2P-N(R3)-P(R4)-NR5R6 or(B) R1R2P-N(R3)-P(XR7)R8 or R1R2P-N(R3)-P(XR7)2, with X═O or S,wherein R1, R2, R3, R4, R5, R6, R7 and R8 are independently C1-C10-alkyl, C6-C20-aryl, C3-C10-cycloalkyl, aralkyl, alkylaryl, or trialkylsilyl, or any cyclic derivatives of (A) and (B), wherein at least one of the P or N atoms of the PNPN-unit or PNP-unit is a member of the ring system, the ring system being formed from one or more constituent compounds of structures (A) or (B) by substitution; and (c) an activator or co-catalyst; and a process for tri- and/or tetramerization.
