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.

Capped multi- or dual-headed compositions useful for chain shuttling and process to prepare the same

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.

Multi- or dual-headed compositions useful for chain shuttling and process to prepare the same

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.

A composition comprising an ethylene/alpha-olefin/non-conjugated polyene, and wherein the ethylene/alpha-olefin/non-conjugated polyene comprises the following property: a '13C NMR % iCB Peak Area,' which is the {[(13C NMR peak area from 34.4 ppm to 34.6 ppm) divided by (the 13C NMR sum integral area from 160.0 to 100.0 and from 60.0 ppm to 0.00 ppm)]&#xd7;100}, that is &#x3e;0.010%, as determined by 13C NMR.
