A transparent, electrically conductive, thermoplastic polymer. Ionomer resins are primarily composed of ethylene copolymerized with small amounts of vinyl and acid (such as methacrylic acid) groups. The copolymer has both covalent and ionic bonds. Ionomers crosslink to form a plastic that is resistant to abrasion, breaking, and chemicals. They are used for break-resistant bottles, vacuum packaging, protective equipment, insulation, sporting goods, and foamed sheets.
