A description is presented of the application of ASAXS to a nickel-neutralized sulfonated polystyrene (NiSPS) ionomer. Results indicate that the ubiquitous zero-order scattering is related to the neutralizing cation, and may be caused by an inhomogeneous distribution of isolated ionic groups in the material. Application of the Debye-Bueche random-two-phase model to the data indicates that a correlation length of order 100 nm, with an electron density difference less than 1% of the aggregate-matrix contrast, can rationalize the data.
