Abstract

It is difficult to form a stable dispersion of selenium of small particle size, e.g. 0.25 p, for use in micro- imaging techniques. The concept of this disclosure involves a process for preparing stable dispersions of selenium by mixing fine particles of selenium with a prepolymer, e.g. styrene, in a solution polymerization system containing from 15 to 50% of the polymer in an organic solvent. Polymerization of the prepolymer to completion while agitating the reaction mass provides a uniform dispersion of selenium in a polymeric matrix which can be broken up to provide particles useful in microimaging.
