摘要：
The present disclosure relates to a process for synthesizing multi- or dual-headed compositions having the formula R1MA[R2MA-]NR1 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.
