ABSTRACT
This chapter explores the three most common types of heterogeneous polymerization: suspension, emulsion, and coordination polymerization. Free radical polymerization can be carried out in bulk or solution, as well as in heterogeneous systems. In bulk polymerization, the viscosity of the monomer/polymer mixture rises very rapidly with monomer conversion. Highly linear stereospecific polyolefins are produced by a class of heterogeneous polymerization processes known as coordination or stereospecific polymerization. Free radical polymerization can be carried out in bulk or solution, as well as in heterogeneous systems. The emulsion polymerization process bas significant advantages over other polymerization processes. Emulsion polymerization is primarily carried out with vinyl monomers via the free radical mechanism. The surface coverage of the particles directly affects the course of the polymerization. Highly linear stereospecific polyolefins are produced by a class of heterogeneous polymerization processes known as coordination or stereospecific polymerization.
