1. A foamed polyolefin composition comprising:
a random cationomeric polyolefin copolymer comprising at least a first monomer and a second monomer, the first monomer being a neutral monomer and the second monomer having a side chain bearing a cationic moiety; and
a gas component disposed in a plurality of voids within the random cationomeric polyolefin copolymer,
wherein the cationic moiety is tethered to a benzylic carbon atom or an allylic carbon atom in the second monomer by a spacer group, and
wherein the random cationomeric polyolefin copolymer comprises a reaction product obtained from a reaction between
1) a random terpolymer of styrene, 4-vinylbenzyl bromide or 4-vinylbenzyl chloride, and isobutylene, and
2) a nucleophilic component selected from the group consisting of a tertiary amine, an N-substituted imidazole, a pyridine, and a tertiary phosphine.
