Abstract

The dynamics of order parameter fluctuations has been investigated near the maximum of the static structure factor for semidilute solutions in a neutral good solvent of a very high molecular weight diblock copolymer. The effect of the proximity to the disorder-to-order transition (ODT) was evident both in the static light scattering intensity and in the internal relaxation by increasing the copolymer concentration up to φODT. An extra relaxation was also observed which can be attributed to curvilinear Rouse motion of the blocks between entanglements inside their tubes.
