Development of Improved Rheometric Tools and their Application on the Non-Newtonian Rheology of Polymeric Fluids

Naue, Ingo F. C.

The normal force and pressure of polymers is studied with improved constructions for rheometers. Via the FT the time-dependent data from oscillatory shear and capillary flows is analysed. A nonlinear parameter is introduced for LAOS and for the melt flow instabilities a FT analysis of the extrudate images is introduced For the CaBER, the elongational viscosity is calculated, the equations of balance are restated and the influence of the curing time is studied using the new separation energy.
