Abstract:

In this communication, we report the results of an experiment in which an ionomer with a microdomain structured characterized by the absence of a small angle x ray scattering maximum herein interpreted as being void of ionic clusters is heated to elevated temperatures. Using the high x ray flux afforded by a synchrotron radiation source, the formation of the cluster morphology in this material was observed as a function of temperature through small angle x ray scattering measurements. To our knowledge, this represents the first time that the development and growth of microphase separation in an ionomer has been reported.
