Inline rheological behavior of dispersed water in a polyester matrix with a twin screw extruder

Solvent‐free extrusion emulsification (SFEE) is a complex process using twin‐screw extrusion to prepare solid‐liquid dispersions of high viscosity polymers and has received little study to date on its inherent mechanisms. To gain rheological insights into the earliest stage of SFEE as the interfacial boundary between water and polymer grows, prior to phase inversion, an inline orifice‐plate type viscometer is introduced to monitor transient …
