• W2023139021 abstract "The concentration dependence of micelle formation by a diblock copolymer of polystyrene-poly(ethylene propylene) (PSPEP) in n-heptane is examined by turbidity, viscosity and photon correlation spectroscopy (p.c.s.). The critical micelle concentration (c.m.c.) as determined by p.c.s. is estimated to be 0.002 wt%. At c = 0.003%, an unusually large hydrodynamic radius is found, in agreement with the anomalous increase in hydrodynamic size near the c.m.c. previously reported by Tuzar et al. in 1985. The average micellar weight obtained from turbidity measurements and the hydrodynamic radius for non-interacting micelles as measured by p.c.s. were relatively constant for c = 0.01–0.5%. A comparison of the second virial coefficients from the turbidity and viscosity measurements suggests that the relatively large Huggins constant of kH = 2.4, obtained from viscosity measurements, may be explained in terms of an excluded-shell model. At a critical concentration above 0.5%, an increasing amount of freely dispersed polymers is present in the solution. The driving force for this change in the free chain-micelle equilibrium is believed to arise from the concentration gradient of PEP segments between the micelle corona and the dispersed phase. The amount of free chains relative to micelles is found to increase from 0.7% up to 2% based on p.c.s. results. It is not clear, however, if the equilibrium is further shifted in favour of the free chains from 3 to 5%, since the weight fractions of free chains and micelles cannot be deduced from p.c.s. data at such high concentrations. However, turbidity and viscosity data seem to suggest that the relative amount of free chains at 3% is lower than that at 2%. At even higher concentrations (4–5%), the viscosity of the micelle solutions increases drastically, presumably because of the formation of a macrolattice." @default.
