Özet:

 

The hydrodynamic properties of micelles formed by 2 block  copolymers of isoprene and tert-butylacrylate in n-octane were  investigated by dynamic light scattering (DLS) over a range of  temperatures and concentrations using both the cumulants and histogram  methods.  By means of the histogram method it was possible to  determine the average hydrodynamic diameters of both micelles and  unassociated-chains in the same solution.  It was also used to  determine the z-average fraction of unassociated-chains at a  particular concentration and temperature, and it provided an  alternative route when combined with static light scattering (SLS) for  determining the thermodynamics of micellisation.  The overall-average  diffusion coefficient, \overline{D}z, values and the average  hydrodynamic diameters, (\overline{dh-1})z-1, of the 2  block copolymers were determined by means of the cumulants method.
