Solution Properties of Micelle Networks Formed by Nonionic
Rheological properties of aqueous solutions of micelle networks formed by a copolymer of sodium 2-(acrylamido)-2-methylpropanesulfonate (AMPS) and an associative macromonomer, methacrylate substituted with HO(CH2CH2O)25C12H25 (C12E25) (20 mol % content in the copolymer), were investigated as a function of the polymer concentration (Cp), added salt concentration ([NaCl]), and shear stress.

HANNAN Union Carbide Corporation, Tarrytown Technical Center, Tarrytown, New York, 10591 Received June 12, 1975; accepted October 15, 1975 The interaction of a water-soluble cationic substituted cellulose ether with sodium dodecyl sulfate (SDS) has been examined through a study of precipitation patterns and measurements
Effects of Dissolved Gases in Surfactant Dissolution Media
Three representative surfactant-containing dissolution media were prepared in water:0.5% sodium dodecylsulfate (Sigma Chemical Co.,St. Louis,MO),2.0% sodium dodecylsulfate and 0.5% Tween 80 (TCI,Tokyo,Japan). The first treatment of media was placed in dissolution vessels immedi-ately after preparation,the media were agitated at 50 rpm using
The propagation stage of the autoxidn. was accompanied by an increase in acid content, and in the termination stage, the nonionic surfactants underwent a decrease in soly. The peroxide formation rate was increased by increasing temp., the presence of Cu [7440-50-8] ions, decreasing pH and surfactant concn., and prior treatments such as

- What is polyacrylamide (PAM)?
- Polyacrylamide (PAM) is a long chain, linear, water soluble polymeric substance formed from acrylamide (C 3 H 5 NO) subunits, has a high molecular weight of typically from few 1000 to 20 × 10 6 g/mol, and has a very high viscosity in aqueous solutions, depending on the concentration and the degree of polymerization (Sojka et al. 2007).
- Can polyacrylamide be bioremediated?
- Although polyacrylamide (PAM) and its derivatives have many useful applications, their release in nature can have impacts on the environment and human health, thus bioremediation approaches for residual PAM are urgently needed.
- Can polyacrylamide contribute to residual polymer formation?
- Common methods for treating PAM are membrane filtration 25, thermal distillation 24, oxidation treatment 26, and biological treatments 27. However, addressing the challenge posed by PAM remains a pressing issue within the industry. Fig. 1: Polyacrylamide and its fragments may contribute to residual polymer formation.
