Abstract

Small angle neutron scattering has been used to investigate the structure
of poly(methylmethacrylate) dispersions in dodecane in the presence of an
electric field. In dodecane alone field effects were not observed. In the presence
of calcium octanoate, however, the particles apparently become charged and
increased ordering was observed. The effect of an electric field on the latter
dispersions produced anisotropy of structure which suggested that the particles
were forming loose “strings of beads” in the direction of the applied field.
