ABSTRACT:
A process for the preparation of polymer particles with an average diameter of from about 0.1 to about 40 microns, which comprises (1) mixing at least one monomer with a free radical polymerization initiator, and an initiator capable of being activated with light, which monomer mixture is dispersed in an aqueous phase containing a surfactant; (2) subjecting the aforementioned mixture of (1) to light irradiation for an effective period of time to accomplish stabilization of the mixture, while initiating photopolymerization of the monomer, and (3) subsequently heating the aqueous phase thereby completing polymerization of the monomer.
