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:[R-A]-Mwherein 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 &#x2212;1 or &#x2212;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.

A suction canister liner including a one-piece liner having a generally cylindrical shape with an open end, a closed end, a sidewall connecting the open end to the closed end, and a rim extending outward generally perpendicular to the sidewall at the open end. An inner surface of the sidewall at the open end of the liner is configured to receive a lid in a sealing engagement and the rim can engage an open-ended suction canister and support the liner within the suction canister.
