Abstract

A process to produce an ionomer comprising reacting alkyl-cis-cyclooctene and cis-cyclooctene in a mole ratio from 1:0 to 0:1, in the presence of a difunctional chain transfer agent under ring opening metathesis polymerization conditions to form an unsaturated polyolefin reactive telechelic pre-polymer; hydrogenating the unsaturated polyolefin reactive telechelic pre-polymer to produce a hydrogenated polyolefin reactive telechelic pre-polymer; reacting the hydrogenated polyolefin reactive telechelic pre-polymer with at least one compound according to the formula aM x ·b(R) y , wherein M is a metal, x is a charge of M, R is an alkyl, aryl, oxide, or fatty acid, y is a charge of R, a and b are integers of at least 1, and ax+by=0, to form an ionomer is provided. Further provided are ionomers produced thereby.

First claim

1 . A process to produce an ionomer comprising:
reacting alkyl-cis-cyclooctene and cis-cyclooctene in a mole ratio from 1:0 to 0:1, in the presence of a difunctional acid chain transfer agent under ring opening metathesis polymerization conditions to form an unsaturated polyolefin reactive telechelic pre-polymer; hydrogenating the unsaturated polyolefin reactive telechelic pre-polymer to produce a hydrogenated polyolefin reactive telechelic pre-polymer; reacting the hydrogenated polyolefin reactive telechelic pre-polymer with at least one compound according to the formula aM x ·b(R) y , wherein M is a metal, x is a charge of M, R is an alkyl, aryl, oxide, or fatty acid, y is a charge of R, a and b are integers of at least 1, and ax+by=0, to form an ionomer.

2 . The process according to claim 1 , wherein the alkyl-cis-cyclooctene is 3-hexyl-cis-cyclooctene.

3 . The process according to claim 1 , wherein the chain transfer agent is selected from the group consisting of maleic acid and dicarboxylic acid.

4 . The process according to claim 1 , wherein cis-cyclooctene is present in the reacting step and the mole ratio of cis-cyclooctene to alkyl-cis-cyclooctene is from 1:0.05 to 0.05:1.

5 . The process according to claim 1 , wherein the reacting occurs in the presence of a Grubbs catalyst and/or any catalyst suitable for ROMP.

6 . The process according to claim 1 , wherein the hydrogenating is catalytic hydrogenation at temperatures between 50 and 80° C. and pressures of 350 to 500 psi wherein the catalyst is a silica supported platinum catalyst.

7 . The process according to claim 6 , wherein the hydrogenating is chemical hydrogenation.

8 . An ionomer produced according to the process of claim 1 .
