โœฆ Synopsis


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, and loss moduli of a polydisperse polystyrene are measured. Molecular weight distribution of the polystyrene is measured by gel permeation chromatography. The

The bulk theological properties of exopolymers produced by three species of microalgae are destroyed by shear stress. The properties are drag reduction in capillary pressure flow and low shear rate viscosity. As such, shear stress constitutes an experimental probe into the macromolecular structure w
