Coextrusion of Multilayer Structures, Interfacial Phenomena

International audienceThe focus of this overview is to give a state-of-the-art knowledge on coextrusion and rheology at the interface of multilayer polymers. In this article, we summarize important experimental and fundamental aspects given in the literature in regard to structure-processing-properties relationships. In addition, the modeling of the interfacial phenomena and the role of the interphase on the flow stability in coextrusion are also discussed
