Abstract
Creep rate spectroscopy has a resolution which allows the separation o f segmental relaxations in a complex polymer system such as a miscible polyurethane/butyl methacrylate copolymer interpenetrating network. T he heterogeneity of segmental dynamics within an anomalous glass trans ition was demonstrated as the discrete manifestation of a few predicte d types of motions, cooperative and non-cooperative.
