    AnotacePhenomena associated with the microdomain morphology in blends of deuterated block copolymers (dPS-block-dPMMA)1/(dPS-block-PMMA)2, were investigated using small-angle X-ray scattering, small-angle neutron scattering and transmission electron microscopy as a function of molecular weight, concentration of added copolymers and temperature. The blends were found to be completely miscible on the molecular level at all compositions, if their molecular weight ratio was smaller than about 5. The domain spacing D of the blends can be scaled with Mn by D Mn2/3 as predicted by a previously published postulate Evidently the postulate, suggested originally for blends of lamellar polystyrene-block-polyisoprene copolymers, can be employed to a much broader range of blends.
