Analysis—requiring no pretreatment—of the core‐shell morphology of polymer latices is achieved by X‐ray small‐angle scattering in combination with ultra‐centrifuge sedimentation. The latter technique is required for the determination of the particle size distribution. For larger scattering angles (g > 0.1 nm −1 ), the measured and calculated scattering intensities agree quantitatively; the differences for the smallest g values may be attributed to interparticle interferences and give information on the interaction of the particles.
