Abstract

See full text

Embodiments of the present invention include a branched aromatic ionomer, and a process of making it, by co-polymerizing a first monomer comprising an aromatic moiety and an unsaturated alkyl moiety and a second monomer represented by the general formula:

description='In-line Formulae' end='lead'[R-AZ]y-MX description='In-line Formulae' end='tail'

wherein R is a hydrocarbon chain having from 2 to 40 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. The branched aromatic ionomer has a melt flow index ranging from 1.0 g/10 min. to 13 g/10 min. Optionally the melt flow index ranges from 1.3 g/10 min. to 1.9 g/10 min.
