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.

First claim

What is claimed is:

1 . A composition having the formula (I) or (II):

wherein:
each MA is Al, B, or Ga;
each MB is Zn or Mg;
m is a number from 0 to 1;
n is a number from 1 to 100; and
each J1, J2, and J3 is hydrogen or a C 1-20 alkyl group, and
wherein J1, J2, and J3 may be the same or different, or mixtures thereof.

2 . The composition of claim 1 , wherein each J1, J2, and J3 is selected from the group consisting of methyl, ethyl, n-propyl, n-butyl, isobutyl, n-hexyl, isohexyl, n-octyl, isooctyl, and isomers thereof.

3 . A process for preparing the composition having the formula (I) or (II):

wherein:
each MA is Al, B, or Ga;
each MB is Zn or Mg;
m is a number from 0 to 1;
n is a number from 1 to 100; and
each J1, J2, and J3 is hydrogen or a C 1-20 alkyl group, and
wherein J1, J2, and J3 may be the same or different, or mixtures thereof, the process comprising: (a) combining 1,2,4-trivinylcyclochexane, an organometallic compound, a co-catalyst, a solvent, and a first catalyst precursor, and (b) obtaining a final solution comprising the composition having the formula (I) or (II).

4 . The process of claim 3 , wherein the organometallic compound comprises a trivalent metal, a divalent metal, or a mixture of a trivalent metal and a divalent metal.

5 . The process of claim 3 , wherein each J1, J2, and J3 is selected from the group consisting of methyl, ethyl, n-propyl, n-butyl, isobutyl, n-hexyl, isohexyl, n-octyl, isooctyl, and isomers thereof.

6 . A polymerization process for preparing a polymer composition comprising:
contacting at least one olefin monomer with a catalyst composition; wherein the catalyst composition comprises the reaction product of a catalyst precursor, a co-catalyst, and the composition of claim 1 .

7 . A polymerization process for preparing a polymer composition, the process comprising:
contacting at least one olefin monomer with a catalyst composition; wherein the catalyst composition comprises the reaction product of a second catalyst precursor, a co-catalyst, and the composition prepared according to the process of claim 3 , and wherein the second catalyst precursor is the same compound as the first catalyst precursor.

8 . A polymer composition obtained by the polymerization process of claim 6 .

9 . A catalyst composition comprising the reaction product of at least one catalyst precursor, at least one co-catalyst, and the composition of claim 1 .

10 . A process for preparing a telechelic functional polymer comprising performing functional group conversion reactions at carbon-metal bonds of the composition of claim 1 .
