摘要：

We discuss the applicability of forced Rayleigh scattering (FRS) as a means of a direct determination of possible diffusional anisotropies on the block copolymer systems with lamellar morphology. We report a first result which directly indicates the anisotropy of diffusion in this system. For this purpose the diffusion measurements were conducted on a bulk poly(styrene-block-isoprene) copolymer (M(n) = 2.12 x 10(4)) in the ordered state and in directions parallel and perpendicular to the surface of an oriented film at temperatures higher than the glass transition temperature of polystyrene microdomains.
