Abstract:
The present disclosure relates to a process for synthesizing multi- or dual-headed compositions having the formula R 1 M A [R 2 M A -] N R 1  by employing a sterically hindered compound and an organometallic compound in the presence of a transition metal catalyst. The present disclosure further relates to use of the compositions, as well as the process to make the same, in olefin polymerization.

Claim (Index 1):
A process for preparing a composition comprising the steps of:\n contacting a sterically hindered diene with an organometallic compound, a solvent, a catalyst precursor, and a co-catalyst to form a final solution containing the composition, wherein the composition has the formula: R 1 M A [R 2 M A -] N R 1 , or an aggregate thereof, a Lewis base-containing derivative thereof, or any combination thereof; wherein: M A  in each occurrence is Zn, Mg, Ga, B, or Al; R 1  in each occurrence is independently selected from hydrogen, alkyl, halide, amide, hydrocarbyl, hydrocarbylamide, dihydrocarbylamide, hydrocarbyloxide, hydrocarbylsulfide, dihydrocarbylphosphido, tri(hydrocarbyl)silyl; any hydrocarbyl group being optionally substituted with at least one halide, amide, hydrocarbylamide, dihydrocarbylamide, or hydrocarbyloxide; and each carbon-containing R 1  having from 1 to 50 carbon atoms, inclusive; R 2  in each occurrence is a derivative of the sterically hindered diene; and N, on average, in each occurrence is a number from 1-150, inclusive.
