| 1964 Mod. Plastics Sept. 98/1 E. I. du Pont de Nemours & Co. Inc. has finally announced the introduction of an exciting new transparent thermoplastic it calls ‘ionomer’. Ibid. 98/2 The tensile strength of many grades of ionomers is higher than that of any commercial polyolefin. 1967 H. F. Mark et al. Encycl. Polymer Sci. & Technol. VI. 395 Another class of copolymers with exceptional properties are the ionomers, which are essentially the metal salts of ethylene-acrylic acid copolymers. The resulting ionic bonding makes these materials a special class. 1967 Times Rev. Industry May 76/2 Among the newer plastics materials offered for use in packaging are ionomer and ethylene/vinyl acetate (EVA) films for meat and other retail produce. |
