SANS and SAXS Study of Block and Graft Copolymers Containing Natural and Synthetic Rubbers


Small-angle neutron scattering (SANS) and small-angle X-ray scattering (SAXS) are excellent techniques to
study nano-scale concentration fluctuations in the two-component polymer systems such as block and graft copolymers
and polymer blends. The miscibility, phase transitions, microphase-separated structures and interface thicknesses were
investigated by SANS and SAXS for the block and graft copolymers, which at least contain natural or synthetic rubber
as one component.
