The structure of a polymeric material can be described at different length scales, from the sub-nm length scale up to the macroscopic one. There is in fact a hierarchy of structures, in which each stage provides the foundations for the next one. The starting point for the description of the structure of a polymer is the identity of its constituent monomers. Next, the microstructure essentially de… Web@Wang and Winnik ~1990!; Yekta et al. ~1995!#. At low polymer concentrations in water, both ends of each chain occupy the same micelle, and the hydrophilic backbone is stretched, forming a loop in such a way that independent flower micelles are formed @Semenov et al. ~1995!#. At higher polymer concentrations there are more micelles in the
