From beads-on-a-string to colloidal aggregation: novel crystallization phenomena in the PEO-SDS system
(1999)The anionic surfactant sodium dodecyl sulfate (SDS) interacts strongly with poly(ethylene oxide) (PEO) in aqueous solution, forming micellar aggregates attached to the polymer chains above the so-called critical association ...

Near-monodisperse, catalytically active, imidazole-containing homooligomers: Synthesis by group transfer polymerization and solution characterization
(1999)Oligomers covering degrees of polymerization up to 23 of 2-(1-imidazolyl)-ethyl methacrylate (ImEMA) were synthesized by group transfer polymerization (GTP) in propylene carbonate and tetrahydrofuran (THF). While GTP ...

Precipitation of a water-soluble ABC triblock methacrylic polyampholyte: effects of time, pH, polymer concentration, salt type and concentration, and presence of a protein
(1999)The solution behavior of a low molecular weight ABC triblock methacrylic polyampholyte with the structure (dimethylaminoethyl methacrylate)8-(methyl methacrylate)12-(methacrylic acid)16 was investigated by turbidimetry. ...

Stabilization of lead sulfide nanoparticles by polyamines in aqueous solutions. A structural study of the dispersions
(2010)Lead sulfide (PbS) nanoparticles have been synthesized in aqueous solutions by a reaction between inorganic lead salts and sodium sulfide and stabilized using the cationic polyelectrolytes branched poly(ethylenimine) (PEI), ...

Study of copper sulfide crystallization in PEO-SDS solutions
(2004)The crystallization of copper sulfide in aqueous supersaturated solutions in the presence of the polymer poly(ethylene oxide), PEO, and the surfactant sodium dodecyl sulfate, SDS, was investigated. In these systems, copper ...
