A Generation of Investigations of Rheology and Structure Development in Polymer Processing: A Personal View

Abstract

We present a critical review on research during the last generation on flow phenomena and structure development occurring in polymer processing operations. This is carried out using the methods of rheology and rheo-optics. We begin with a critical discussion of the rheological behavior of bulk polymer systems including flexible chain and liquid crystalline polymers as well as particle filled compounds. Experimental studies and theoretical models are considered. The characterization of molecular orientation is then carefully considered. Advances in process technology are reviewed and application to a range of processing operations including extrusion through dies, melt spinning, film extrusion, injection and blow molding and two phase melt flow including mixing are then critically discussed.
