Abstract
The present disclosure relates to a multi- or dual-headed composition having the formula (I) or (II). The present disclosure also relates to a process for preparing the multi- or dual-headed composition having the formula (I) or (II), the process including combining 1,2,4-trivinylcyclochexane, an organometallic compound, and a catalyst precursor. The present disclosure further relates to use of the composition having the formula (I) or (II) in olefin polymerization.
