    摘要: A mixed metal-containing precursor is disclosed whereby the precursor includes: a) a mixed metal component represented by the following formula: (M1M2)x(T1T2)y where M1 and M2 may be the same or different and are selected from one or more metals having a null2 oxidation state, T1 and T2 may be the same or different and are selected from one or more metals having oxidation states selected from the groups consisting of null3, null4, and null5, the molar ratio of x/y is from about 2.5 to about 3.75, with the proviso that if M1 and M2 are both Mg then T1 and T2 cannot both be chosen from Zr and Tinull4; and b) at least one moiety complexed with component a) selected from alkoxide groups, phenoxide groups, halides, hydroxy groups, carboxyl groups, amide groups, and mixtures thereof. A polymerization procatalyst prepared from the mixed metal containing precursor, methods of making the precursor and procatalyst, as well as polymerization methods using the procatalyst also are disclosed.
