摘要： The present disclosure relates to a capped, multi- or dual-headed chain composition comprising derivatives of a strained olefin. The present disclosure further relates to a process for synthesizing the capped, multi- or dual-headed composition by using an organometallic compound and a co-catalyst in the presence of a catalyst precursor and a strained olefin. The present disclosure further relates to use of the compositions, as well as the process to make the same, in olefin polymerization.
