We report about self-diffusion experiments on a compositionally asymmetric poly(ethylene-co-propylene)-block-poly(dimethylsiloxane) diblock copolymer exhibiting the lamellar and the gyroid morphology. The most probable self-diffusion coefficients and the values calculated for a hypothetical disordered diblock copolymer melt are lower than the self-diffusion coefficients of the constituent homopolymers having the same molar mass.
