Homopolymer systems, Journal of Applied Polymer Science, 10.1002/app.1971.070151022, 15, 10, (2567-2577), (2003). Synthetic polymer fluids are becoming a popular replacement for bentonite slurries to support excavations for deep foundation elements. However, the rheological properties of the polymer fluids used in excavation support have not been studied in detail, and there is currently confusion about the choice of mathematical models for this type of fluid.

Rheological instrumentation has developed to the point where low cost Polyelectrolyte complexes of sodium alginate and gelatin obtained from cold-blooded fish were studied for potential application as structure-forming agents in food hydrogels. The mass ratio of sodium alginate to gelatin plays a decisive role in the sol-gel transition and rheological behavior of the complexes.

Polymers show complex rheological behavior which needs to be considered when using or producing these kinds of materials, like the viscosity of the melt, flow behavior, viscoelastic properties, temperature-dependent behavior, glass transition temperature, aging behavior, etc. Various tests and analysis methods are employed to optimize the polymer properties until they meet all requirements. Polymer Behavior Larson, Ron, The Structure and Rheology of Complex Fluids (Oxford, 1999) Ferry, John, Viscoelastic Properties of Polymers (Wiley, 1980) Descriptive Rheology Barnes, H., J. Hutton, and K. Walters, An Introduction to Rheology (Elsevier, 1989) Suspension Behavior Larson, Ron, The Structure and Rheology of Complex Fluids (Oxford, 1999) After analyzing a large number of literatures on the viscosimetric and rheological behaviors on polymers and hybrid nanocomposite polymers, we have concluded the following points: The viscosity properties increase by increasing of the percentage of polymer in the (polymer/solvent) systems. Measurements of the rheological properties offer a fast and reliable way to determine molecular weight distribution and long-chain branching, which, in combination with the processing conditions, Polymer rheology is an enormously sensitive indicator of polymer long-chain branching, and consequently can be exploited as a tool to evaluate polymer structures. Carbonaceous fillers are most abundantly used filler due to its reinforcing nature and its low cost.
