Case 7735A(2) ABSTRACT OF THE DISCLOSURE POLYMERIZATION CATALYST AND PROCESS Olefin polymerization catalysts capable of polymerizing olefins such as ethylene to polyolefins with broad molecular weight distributions are made by depositing on an oxide suport (or especially phosphate derivative thereof) (i) a chromium complex of formula RCr-L, where R is optionally substituted pentadienyl or cyclopentadienyl and L is a reactive ligand, or a bis arene chromium and (ii) a metal complex of formula MR3 R4 R5 R6 wherein M is Ti, Zr or Hf, and R3-R6 can be allyl (when M is Zr or Hf) or of 4-20 carbons of formula (a) CH2 X (R7 R8 R9) where X = C, Si or Ge and R7-R9 are hydrocarbyl, or (b) CH2 Ar where Ar is optionally substituted aromatic, or said metal complex is of formula Ti R11 R12, where R11 and R12 are acyclic dienyl.
