Diblock copolymer dynamics

Three aspects of block copolymer dynamics are reviewed with emphasis on the influence of the proximity to the disorder-to-order transition. The relaxation of composition fluctuations in disordered diblocks is discussed over the whole range of wavevectors. The translational motion of individual copolymer chains is reviewed both with respect to the effects of ordering on the long-time diffusional motion and on the motion for short time- and length-scales. Finally, the behavior of the block orientational relaxation is briefly summarized.
