Abstract
The present disclosure relates to a process for synthesizing a multi- or dual-headed composition by using an alpha,omega-diene and an organometallic compound in the presence of a catalyst precursor. The present disclosure further relates to use of the compositions, as well as the process to make the same, in olefin polymerization.
