New lonomer Types. There is a continuing interest in new ionomers within the academic community, since novel and unexpected phenomena are frequently being discovered. However, there are still many unanswered questions with respect to the ethylene ionomers, especially the influence of ionic bonding on crystalline stmcture. Continued study of these interesting polymers will close the gaps in knowledge of this area of polymer science.

Sulfonated EPDMs are formulated to form a number of rubbery products including adhesives for footwear, garden hoses, and in the formation of calendered sheets. Perfluori-nated ionomers marketed as Nation (DuPont) are used for membrane applications including chemical-processing separations, spent-acid regeneration, electrochemical fuel cells, ion-selective separations, electrodialysis, and in the production of chlorine. It is also employed as a solid -state catalyst in chemical synthesis and processing. lonomers are also used in blends with other polymers.
