Abstract

There are basically three types of particle producing polymerization methods: emulsion, dispersion, and suspension. All three methods involve a particle of polymer stabilized by a dispersing agent of some type. In emulsion polymerization the monomer is insoluble in the polymerization medium (usually water) and the polymerization occurs within a surfactant micelle. The typical particle size of an emulsion is in the neighborhood of 0.1 to 0.5 µm. Suspension polymerization involving the use of monomer droplets in water, is carried out with an initiator which is soluble in the monomer and the resulting polymer particles are stabilized by a polymeric suspending agent, e.g., poly(vinyl alcohol). The typical particle sizes obtained by suspension polymerization are usually greater than 100 µm.
