ABSTRACT:
This invention relates to a catalyst system comprising:an activator, such as an aluminum alkyl, alumoxane or combinations thereof;a first catalyst precursor prepared by contacting compound (I) represented by the formula:with an optionally substituted alkyl or optionally substituted aryl alcohol;whereinZ—O is a support material, where O is oxygen and Z is Si, Ti, Al, Sn, Fe, Ga, Zr, B, Mg or Cr;each X is, independently, nitrogen, oxygen phosphorous, or sulfur, provided that both X's are not each oxygen;each n is, independently, 1 or 2, provided the total of n=3;each R is, independently, an alkyl group, a substituted alkyl group, an aryl group, or a substituted aryl group, provided at least one R group is an aryl or substituted aryl group; anda second catalyst precursor, wherein the second catalyst precursor is a metallocene compound.This invention also relates to the use of the above catalyst system to polymerize olefins and other monomers.
