Abstract
A catalyst composition comprising (i) a metal salt complex of an imine bis(phenol) compound characterized by Structure 1: Wherein O and N represent oxygen and nitrogen respectively; R comprises a halogen, a hydrocarbyl group, or a substituted hydrocarbyl group; R2 and R3 can each independently be hydrogen, a halogen, a hydrocarbyl group, or a substituted hydrocarbyl group; and Q is a donor group; and (ii) a metallocene complex.
Claims20
A catalyst composition comprising:
