摘要：

The ordered structure of polymethylmethacrylate-based latex particles in water dispersions have been studied by the Bonse-Hart type Ultra-small-angle X-ray scattering (USAXS) technique. The scattering patterns resembled a "powder diffraction pattern and distinct diffraction peaks were observed in the scattering curve. The lattice system was concluded to be a face-centered-cubic (fcc) lattice from the relative peak position. These findings indicate that the ordered structure has a limited size and that each ordered region orients randomly in the dispersion.
