Micellisation de copolymères séquencés polystyrène‐polyvinylpyridinium, 2. Influence des caractéristiques moléculaires des copolymères

摘要: The influence of the molecular characteristics polystyrene-poly(4-vinyl-N-ethylpyridinium bromide) block copolymers (PS-PVPQ) on their dilute solution properties is investigated in a solvent selective for polyelectrolytic moieties (water-methanol-0,1 mol/1 LiBr mixtures). It shown that association degree depends much more upon length insoluble hydrophobic part macromolecule than soluble hydrophilic part. Micelle dimensions could not be determined from light scattering measurements because compactness particles. Attempts calculation micelle size were made using star-like micellar model.
