TL;DR: In this paper, the surface tension method was applied to a mixture of a highly surface-active species, the surfactant, and a feebly surfaceactive material, the polymer.
648 citations
TL;DR: In this article, the equilibrium surface tension appeared to be solely dependent on the sodium dodecyl sulfate concentration, that is, was independent of that of polylysine, within the limits of the concentrations employed.
511 citations
TL;DR: In this article, a group of three silicone surfactants using surface tension, wetting, adsorption, fluorescence and fluorescence decay techniques were investigated. And the results showed that two of them exhibit a c.m.c. type break in the surface tension versus concentration plot, which corresponds to the formation of well dispersed droplets rather than micelles.
150 citations
TL;DR: In this article, the interaction of sodium dodecyl sulfate (SDS) with two cationic polyelectrolytes, Polymer JR and Reten, was investigated, and the results indicated that small additions of SDS to polymer JR of 1% concentration lead to intermolecular interactions between the polymer chains via the bound surfactant.
81 citations
TL;DR: In this paper, the interaction of a variety of surfactants with a hydrophobically modified cationic cellulosic polymer has been studied by solubility, rheology and surface tension methods.

TL;DR: Although most of the work involves gels based on poly(N-isopropylacrylamide), other polymers are also considered and core-shell latex particles exhibiting temperature-sensitive properties are also described.

TL;DR: In this article, a review of the recent developments in the field of water-soluble polymers aimed at enhancing the aqueous solution viscosity is presented along with a critical overview of the synthetic methods as well as the solution properties of these polymers.

TL;DR: In this paper, the stability of α-Al2O3 suspensions with Na+ salt of poly(methacrylic acid) (PMAA-Na) polyelectrolyte was studied as a function of pH.
Abstract: Stability of aqueous α-Al2O3 suspensions with Na+ salt of poly(methacrylic acid) (PMAA-Na) polyelectrolyte was studied as a function of pH. At a given pH, the transition from the flocculated to the dispersed state corresponded to the adsorption saturation limit of the powders by the PMAA. As the pH was decreased, the adsorption saturation limit increased until insolubility and charge neutralization of the PMAA was approached. The critical amount of PMAA required to achieve stability is outlined in a stability map.
