Catalyst support method and polymerization with supported catalysts

A method to support one or more catalyst compounds comprising contacting the catalyst compounds with a pretreatment agent, selected from the group consisting of aluminum alkyls, alumoxanes and mixtures thereof, in solution, and thereafter contacting the combination with a supported activator, wherein at least one of the catalyst compounds is represented by the formula:

• wherein
• M is a Group 3 to 14 metal,
• each X is independently a leaving group
• y is 0 or 1,
• n is the oxidation state of M,
• m is the formal charge of the YZL or the YZL′ ligand,
• L is a Group 15 or 16 element,
• L′ is a Group 15 or 16 element or Group 14 containing group,
• Y is a Group 15 element,
• Z is a Group 15 element,
• R1 and R2 are independently a C1 to C20 hydrocarbon group, a heteroaton-containing group having up to twenty carbon atoms, silicon, germanium, tin, lead or phosphorus,
• R3 is absent or a hydrocarbon group, hydrogen, a halogen, a heteroatom containing group,
• R4 and R5 are independently an alkyl group, an aryl group, substituted aryl group, a cyclic alkyl group, a substituted cyclic alkyl group, a cyclic aralkyl group, a substituted cyclic aralkyl group or multiple ring system,
• R1 and R2 may be interconnected to each other, and/or R4 and R5 may be interconnected to each other,
• R6 and R7 are independently absent, or hydrogen, an alkyl group, halogen heteroatom or a hydrocarbyl group,
• R* is absent, or is hydrogen, a Group 14 atom containing group, a halogen, a heteroatom containing group.

A method to support one or more catalyst compounds comprising contacting the catalyst compounds with a pretreatment agent, selected from the group consisting of aluminum alkyls, alumoxanes and mixtures thereof, in solution, and thereafter contacting the combination with a supported activator, wherein the catalyst compound comprises a bulky ligand metallocene compound of the general formula LDMQ2(YZ)Xn

• wherein M is a Group 3 to 16 metal;
• LD is a bulky ligand that is bonded to M;
• each Q is a univalent anionic ligand independently bonded to M;
• Q2(YZ) forms a unicharged polydentate ligand;
• Y is either C or S;
• Z is selected from the group consisting of —OR, —NR2, —CR3, —SR, —SiR3, —PR2, —H, and substituted or unsubstituted aryl groups, with the proviso that when Q is —NR— then Z is selected from one of the group consisting of —OR, —NR2, —SR, —SiR3, —PR2 and —H;
• X is a univalent anionic group when n is 2 or X is a divalent anionic group when n is 1;
• and
• n is 1 or 2.
