Feng Jung Wu, Jamie R Strickler: Transition metal compounds having conjugate aluminoxate anions and their use as catalyst components. Albemarle Corporation, Philip M Pippenger, December 12, 2000: US06160145 (6 worldwide citation)

Novel, highly effective catalyst compositions are described in which a low cost co-catalyst can be employed at very low aluminum loadings. Such compounds are composed of a cation derived from d-block or f-block metal compound, such as a metallocene, by loss of a leaving group, and an aluminoxate ani ...
