Abstract:
1. An olefin polymerization or oligomerization catalyst system comprising the reaction product of: (a) an activator selected from the group consisting of alumoxane, aluminum alkyl, alkyl aluminum halide, alkylaluminum alkoxide, boron compounds, hexafluoro phosphorus compounds, hexafluoro antimony compounds, and hexafluoro arsenic compounds; and (b) a catalyst precursor having the following formula: wherein: (i) M is Ni, Fe, Co, Pd, or Pt; (ii) N is nitrogen and is bonded to M; (iii) P is phosphorus and is bonded to M; (iv) R (v) R (vi) Y is butenyl or has one of the following formulas: (vii) X are independently selected from the group consisting of chloride, bromide, iodide, methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, dodecyl, methoxide, ethoxide, dimethylamide, diethylethoxide, and phenoxide, wherein the olefin polymerization or oligomerization catalyst system exhibits an activity that exceeds 8000 moles of ethylene per mole of M per hour.
