THE MORPHOLOGY AND PROPERTIES OF IONOMER

The advance in synthesis and application of ionomer was reviewed in this paper. The morphology of ionomer is unique because of multiplets and ionic clusters formed by aggregation of ionic pairs. Morphology character of ionomer and principal factor such as nature of the host polymer, nature of ionic pairs, heat history, temperature etc. affecting morphology were studied. The models of morphology were also reviewed. The mechanics, dielectric and solution properties resulting from specific morphology were presented in this paper. The presence of multiplets and ionic clusters make ionomer better suited for some specific application, such as food package, insulation material, polymer improvement etc..
