Claims27
A method of preparing a polymerization catalyst comprising combining a bulky-ligand metallocene or a Group 15 containing polymerization catalyst with an alternating Group 14 and Group 16 containing oil or amorphous solid to form a catalyst solution or emulsion;
- wherein the alternating group 14 and Group 16 atom containing oil or amorphous solid is represented by the formulae:
- T-M(R1)2-Q-(M(R2)2-Q)n-M(R1)2-T or T-M(R1)2-Q-(M(R2)2-Q)n-(M(R3)2-Q)m-Si(R1)2-T
- wherein each T, R1, R2, and R3 is independently selected from the group consisting of hydride, alkyl, alkoxy, aryl, substituted aryl, cycloalkyl, substituted cyclic alkyl, cyclic arylalkyl, substituted cyclic arylalkyl, heteroatom, vinyl, silyl, silyloxy, vinylsiloxy, haloaryl, haloalkyl, or vinylsilyl containing group;
- each M is independently an atom of Group 14 of the periodic table;
- each Q is independently an atom of Group 16 of the periodic table;
- and wherein n and m independently an integer between about 1 and 40,000.
