Abstract:
1. A continuous stirred tank reactor system for the production of toner particles by emulsion aggregation, comprising: at least one feed tank of raw materials; at least one reactor comprising an aggregating resin; optionally at least one reactor comprising a shell material; at least one reactor, wherein particle aggregation is frozen therein; optionally at least one reactor comprising a chelating agent; at least one reactor, wherein content temperature therein is increased; and at least one reactor, wherein particles are coalesced therein; wherein the reactors are sequentially assembled in a series configuration, each of the reactors operating with a mechanical agitator, and wherein toner particles are produced by said reactors in series with a space time yield of from about 10 g particles/L/hr to about 500 g particles/L/hr.
