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. Crystallinity and Linear Rheological Properties of Polymers. based on the observation that the same amount of crystallinity induces the same rheological hardening to the polymer, Rheological Properties of Associative Star Polymers in Aqueous Solutions: Effect of Hydrophobe Length and Polymer Topology.

In this study, the effect of polymer structure, the degree of hydrolysis, chemical structure of monomer in the backbone, and charge distribution of monomer groups on rheological and filtration properties of Bentonite (Bent)/polymer dispersions were assessed. Two different water-soluble polymers were employed to investigate the rheological and filtration properties of Bent/polymer dispersions. 2021-04-05 Rheological properties of an ultra-high salt hydrophobic associated polymer as a fracturing ﬂuid system† Jinhao Gao, a Guanghua Zhang,*a Lei Wang,a Li Ding,b Huaqiang Shi,b Xiaojuan Lai,a Xin Wen,a Shaoyun Maa and Chuanqing Huanga Herein, a novel ultra-high salt hydrophobic associated polymer, UUCPAM, was prepared using acrylamide, 9 i. . . 9 jk W R a W R h Wi Ro Ri Wi¹0 : Searl system Wi¹0 : Couette sys.

Then, the rheological properties of the composites are evaluated at the temperature between melting points of PLA and PBT. It is found that only 1 wt. % of PBT fibers greatly enhances the elongational viscosity, Ferry, J. D., Viscoelastic Properties of Polymers, 3rd ed. (Wiley-Interscience, New York, 1980).

Rheological properties of the EVA polymer modified bitumens The rheological parameters should be obtained within the linear viscoelastic range, which is similar to the road traffic loading conditions [5]. It was considered quite interesting to compare the rheological behaviour with base bitumen and EVA modified bitumens. Polymers exhibit non-Newtonian fluid rheological behavior when the viscosity decreases and the shear rate increases (Hirasaki & Pope, 1974). Polymers flowing through porous media may display one of the following four flow regimes: Newtonian, shear thinning, shear thickening, and degradation.
