Abstract:
The present invention relates to a catalyst composition comprising: (a) a binuclear chromium(II) complex; (b) a ligand of the general structure (A) R1R2P—N(R3)—P(R4)—N(R5)—H or (B) R1R2P—N(R3)—P(R4)—N(R5)—PR6R7, wherein R1, R2, R3, R4, R5, R6 and R7 are independently selected from halogen, amino, trimethylsilyl, C1-C10-alkyl, aryl and substituted aryl, wherein the PNPN- or PNPNP-unit is optionally part of a ring system; and (c) an activator or co-catalyst, as well as to a process for oligomerization of ethylene.
