rheological model of Carreau is modified with molecular-weight-dependent relaxation times to obtain rheological functions of the polydisperse polystyrene. It is found that five parameters in the model can satisfactorily describe the rheological functions measured. Non-Newtoniun viscosity, storage,
Polystyrene is not normally shear-modifiable. Addition of small amounts of plasticizer (butyl benzyl phthalate) result in changes in melt viscosity and elasticity during extrusion. Fiber spinning experiments are shown to provide useful indications of the rheological state of polymers that are sensit
