Characterization of Unimolecular Micelles of Random Copolymers of Sodium 2-(Acrylamido)-2-methylpropanesulfonate and Methacrylamides Bearing Bulky Hydrophobic Substituents
TL;DR: In this paper, the self-organization of random copolymers of methacrylamides bearing bulky hydrophobic groups, such as lauryl (LA), cyclododecyl (CD), and 1-adamantyl (AD), was investigated by fluorescence, NMR relaxation, FTIR, light scattering, and SAXS techniques.
Journal ArticleDOI
Micelle Formation of Random Copolymers of Sodium 2-(Acrylamido)-2-methylpropanesulfonate and a Nonionic Surfactant Macromonomer in Water As Studied by Fluorescence and Dynamic Light Scattering
TL;DR: A polyelectrolyte-bound nonionic surfactant (HO(CH2CH2O)25C12H25) (C12E25) system was prepared by copolymerization of sodium 2-(acrylamido)-2-methylpropanesulfonate (AMPS) and a methacrylate substi...

Solution Properties of Micelle Networks Formed by Nonionic Surfactant Moieties Covalently Bound to a Polyelectrolyte: Salt Effects on Rheological Behavior
TL;DR: In this article, the authors investigated the properties 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 copolymers), were investigated as a function of the polymer concentration (Cp), added salt concentration ([NaCl]), and shear stress.
Journal ArticleDOI
Heat-Induced Association and Dissociation Behavior of Amphiphilic Diblock Copolymers Synthesized via Reversible Addition−Fragmentation Chain Transfer Radical Polymerization
TL;DR: A water-soluble diblock copolymer was prepared from sodium 2-(acrylamido)-2-methylpropanesulfonate (NaAMPS) and N-isopropylacryamide (NIPAM) via reversible addition-fragmentation chain transfer (RAFT) controlled radical polymerization as discussed by the authors.

TL;DR: In this article, the association behavior of random copolymers of AMPS and DMA with its content varying from 1 to 15 mol % was investigated by fluorescence and quasielastic light scattering (QELS) techniques in 0.1 M NaCl aqueous solutions.
