摘要: Publisher Summary This chapter presents the recent applications of polarized and depolarized first-order (single) light scattering to interacting nondilute polymer systems. It also provides an overview diblock copolymers, AB, which are thermodynamically single-component systems with chemically dissimilar sequences NA monomers A NB B that unlike binary blends, A/B, cannot macrophase separately. For very high molecular mass diblocks, order-to-disorder transition is approached by increasing copolymer concentration in a common solvent at constant temperature. The identification rational combination distinct features different classes soft can facilitate design new materials intermediate properties. Polymers colloids two such materials. relevant length scale fluctuations semidilute linear flexible polymers small independent N, represents size self-avoiding segment.
