This document provides an introduction and overview of polyacrylamide emulsions. It discusses that emulsions are dispersions of a hydrogel polymer in an oil phase, stabilized by surfactants. They differ from powders in being simpler to handle but more complex multicomponent products. The document outlines contents to guide users on proper storage, handling, production of polymer solutions from ...

Do polymers affect emulsifying stability of amphoteric polyacrylamide (tspam)?

The role of polymers in the emulsifying stability of an amphoteric polyacrylamide (TSPAM) with good viscosity–temperature property in different flooding systems was investigated by means of a new emulsion stability model and molecular simulations.

Does tspam enhance emulsion stability?

TSPAM, in combination with Na 2 CO 3 and surfactants, exhibits a strong synergistic effect in enhancing the emulsion stability.

Are polymers good emulsifying agents for enhanced oil recovery?

This article has not yet been cited by other publications. Polymers with high viscosity and good viscosity–temperature property have attracted attention as chemical agents for enhanced oil recovery. The role of polymers in the emulsifying stability of an a…

Does polymer concentration affect stability of simulated emulsion containing Alkali–Surfactant–Polymer Flooding system?

The influence of polymer concentration on the stability of the simulated emulsion containing the alkali–surfactant–polymer flooding system was investigated at SDBS 0.3 wt % and alkali 1.2 wt %, as shown in Figure 8 and Table 4.

Why is emulsion stability important in a flooding system?

(6) The results of the flooding tests showed that the emulsion stability of the flooding system containing polymer plays an important role in the chemical EOR, and the emulsion stability of the flooding system was influenced not only by the viscosity of the solution but also by the chemical structure and the concentration of the polymer.

Does comb shaped polymeric surfactant emulsify?

Rui Zhang and co-workers (19) investigated the emulsification properties of a comb-shaped polymeric surfactant by emulsification rate experiments and low-field nuclear magnetic analysis and characterized the emulsion stability by the relaxation time area and peak spacing.
