"Disentanglement "of Polymer Melts in a Dynamic Rheometer. YEAR + 14 Perspectives

In this video presentation , we introduce the subject of "disentanglement" to describe triggered transients in dynamic experiments. In part II of the Great Myths of Rheology (J. of Macromol. Sci. Part B, 49, 6, 1149-1258 (2010), I explain why these transients cannot be resulting from surface effects or artifacts. Middway through this lecture (~26 min to the end) I discuss the basic assumptions of my new model of interactive coupling leading to the Dual-Phase split and the definition of the entanglement network. Part II and Part IV of the Great Myths of Rheology are devoted to the description of the network elasticity and of Dual-Phase Viscoelasticity.
