Rheology of Hydrophobically Modified Polyacrylamide-co
The effect of the ionic strength on the rheological behavior of hydrophobically modified polyacrylamide aqueous solutions mixed with sodium dodecyl sulfate (SDS) or cetyltrimethylammonium p-toluenesulfonate (CTAT).
The term “polyacrylamide” is loosely used to describe any polymer with acrylamide present as one of the monomers. 1 More rigorously, its IUPAC nomenclature is poly (prop-2-enamide), which
Rheological and mechanical behavior of polyacrylamide
Research PaperRheological and mechanical behavior of polyacrylamide hydrogels chemically crosslinked with allyl agarose for two-dimensional gel electrophoresis. Rheological and mechanical behavior of polyacrylamide hydrogels chemically crosslinked with allyl agarose for two-dimensional gel electrophoresis.
The rheological behavior of viscoelastic fluids was investigated with regard to the specialty of tertiary oil recovery. Aqueous polyacrylamide solutions at different concentrations were selected to simulate viscoelastic polymer systems, and the Haake RS 150 type rheometer was used to measure the rheological behavior.
Rheological properties of syndiotacticity‐rich ultrahigh
Consequently, the dilute solution of UHMW s‐PVA/DMSO/water showed the rheological behaviors as can be observed in general chemical or physical gel systems below the critical temperature. These results suggest that solid‐like heterogeneity prevailed in the solution before macroscopic gelation with decreasing temperature.

Rheology of a concrete is mainly controlled by the rheological behavior of its cement paste. This is the main practical reason for the extensive research activity observed during 70 years in this research subfield. In this brief review, some areas of the research on the rheological behavior of fresh cement pastes (mixture method influence, microstructure analysis, mineral additions influence

- Why is anionic polyacrylamide chosen?
- Anionic polyacrylamide is chosen because the intramolecular electrostatic repulsion between polymer segments forces the polymer chains to adopt a more extended conformation, increasing the efficiency of bridging flocculation.
- Does anionic polyacrylamide biodegrade?
- ent only.1 BACKGROUNDAnionic polyacrylamide is the copolymer of acryl mide and acrylic acid. No studies on the environmental fate of polyac ylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biode rade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concer
- What is anionic polyacrylamide (Apam)?
- 1. Introduction Anionic polyacrylamide (APAM) is a kind of organic high-molecular polymer with high hydrophilicity and viscosity, which is easily dissolved in water [ , , ].
- Is polyacrylamide a cationic or nonionic polymer?
- rade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concer CO-CHEMICAL PROPERTIESPolyacrylamide polymers can exist in cationic, anionic or non-ionic forms, depending on their ionic charge. The non-ionic form of polyacrylamide is generated from the basic polyme
