摘要： A catalyst composition including: (a) a chromium compound; (b) a ligand of the general structure R1R2P—N(R3)—P(XR7)2, wherein X is O or S, R1, R2, and R3 are each independently C1-C10-alkyl, C6-C20-cycloalkyl, arylalkyl, alkylaryl, or trialkylsilyl, or any cyclic derivatives of the ligand, wherein at least one of the P or N atoms of the PNP-unit is a member of the ring system, the ring system being formed from one or more constituent compounds of the ligand by substitution, and R7 is C1-C10-alkyl, C3-C10-cycloalkyl, arylalkyl, or trialkylsilyl; and (c) an activator or co-catalyst.
