The micellization of amphiphilic graft copolymer PMMA-g-PEO in toluene

摘要

The micellization of amphiphilic graft copolymer PMMA-g-PEO in selective solvent, toluene, was examined by means of H-1-NMR and viscometry. Micelle formation of PMMA-g-PEO in toluene was strongly dependent on the concentration and temperature. An increase in temperature shifted the micelle formation markedly to tower concentration. The viscosity data were analyzed to estimate the cmc value, the cmc value was affected by the PEO content and the PEO side chain lengths in PMMA-g-PEO amphiphilic graft copolymers.
