Abstract:
1. A branched aromatic ionomer comprising the product of co-polymerizing a first monomer comprising an aromatic moiety and an unsaturated alkyl moiety and 1 pph or less of a second monomer comprising an ionic moiety and at least two unsaturated moieties, wherein the ionic moiety has at least two ionizable groups, a cationic group that ionizes to form cations and an anionic group that ionizes to form anions, and wherein the cationic group is poly-valent and one capable of forming bridges to other molecules; and wherein the second monomer is comprised of a compound having a formula of:  where: R is a hydrocarbon chain having from 2 to 7 carbons and at least one polymerizable unsaturation, A is an anionic group, M is a cationic group, Z is −1 or −2, X is +1, +2, +3, +4, or +5, and y is an integer having a value of from 1 to 4.
