Linear alkylbenzene sulfonate (NaLAS) surfactant is often combined with polycarboxylate polymers in detergent formulations. However, the behavior of these aqueous surfactant-polymer systems absence an added electrolyte unreported. This work investigates such using polarized light microscopy, small-angle X-ray scattering (SAXS), centrifugation, and 2H NMR techniques. A phase diagram at 50 °C rep...

This study presents a new approach that can stabilize effectively L-ascorbic acid in water-in-oil-in-water (w/o/w) double emulsions. Basically, the behavior of L-ascorbic acid in the aqueous phase was observed, considering its molecular deformation. Then, it was found that the stability determined in the aqueous phase by high-performance liquid chromatography (HPLC) showed that the collapse of ...

a new potassium persulfate redox system has been investigated for the graft polymerization of vinyl monomers. in this study potassium persulfate system was used for initiation the polymerization. graft polymerization of acrylonitrile (an) onto starch (sta) was carried out in aqueous solution using potassium persulfate (i) redox system. it was found that the percentage of grafting and rate of gr...
