Abstract:DMA is a tool for studying linear viscoelastic behavior of polymers over ranges of temperature and frequency. Viscoelasticity has its origin in the complex molecular behavior of the polymer. A theoretical master curve has been constructed, based predominantly on thermodynamic theories of polymer molecular conformations, and their intermolecular cooperativity.This revised version was published online in November 2005 with corrections to the Cover Date.
Keywords:cooperativity  entanglement  entropy  free volume  glass transition  viscoelasticity
