Abstract
The polymer mode-coupling theory is extended to describe diffusion in block copolymer melts. Concentration fluctuations are shown to significantly slow down the diffusion near or below the order-disorder transition temperature. These effects are stronger for longer tracers, and for homopolymer tracers compared with block copolymer tracers. Quantitative agreement is obtained between our theory and recent experiments.
