Phase Transitions in Polymer Systems

Phase Transitions in Polymer Systems. Most products utilize polymers in their bulk (solid, condensed) state. For these applications, physical properties are strongly dependent on phase morphology and, as a result, on temperature. To clarify key concepts, we will handle a few different polymers:
