Popis:	We investigate the small-angle light scattering from dilute polystyrene (PS)-poly(dimethylsiloxane) (PDMS) diblock copolymers in semidilute isorefractive PDMS/tetrahydrofuran (THF) solutions. We compare the results with those obtained on PS/PDMS homopolymer mixtures and analyse the data quantitatively in terms of the only available theoretical results based on the mean-field approach. We also obtain measurements of diffusion coefficients of probe PS molecules and probe PS-PDMS diblock molecules in semidilute PDMS/THF solutions by dynamic light scattering and show the different coupling that occurs between the probe molecule and the semidilute matrix.
