Abstract
The micellization of amphiphilic graft copolymer polystyrene-graft-poly(eth ylene oxide) (PS-g-PEO) in selective solvent, toluene, was studied by means of H-1-NMR, TEM and viscometry. Micelle formation of PS-g-PEO in toluene w as strongly dependent on concentration and temperature. An increase in temp erature shifted the micelle formation markedly to lower concentration. The micelle was formatted at certain concentration, and it was spherical struct ure. The viscosity data were analyzed to estimate the cmc value.
