description 12341 3 2 4 1′2′3′4′1′2′3′4′A catalyst precursor composition comprising a) a source of chromium, molybdenum or tungsten; b) a first ligand having the general formula (I): (R)(R)P-X-P(R)(R)  (I) where X is a bivalent organic bridging group, Rand Rare hydrocarbyl groups, and Rand Rare aromatic groups; and c) a second ligand having the general formula (II): (R)(R)P-X′-P(R)(R)  (II) where X′ is a bridging group containing nitrogen and R, R, R and R are hydrocarbyl groups. The present invention also relates to a catalyst system comprising the catalyst precursor composition of the present invention and a cocatalyst.
