    Emulsion polymerization

    One of the earliest methods of industrial production of PVC. In the emulsion polymerization, in addition to water and vinyl chloride monomer, a surfactant such as sodium alkylsulfonate is added as an emulsifier to disperse the monomer in the aqueous phase to form an emulsion, which is water-soluble potassium persulfate or Ammonium persulfate is used as an initiator, and an "oxidation-reduction" initiation system can also be used, and the polymerization process and suspension method are different. There are also polyvinyl alcohol as an emulsion stabilizer, dodecyl mercaptan as a regulator, and sodium hydrogencarbonate as a buffer. There are three methods of polymerization: batch method, semi-continuous method and continuous method. The polymerization product is in the form of a latex, and the emulsion has a particle diameter of 0.05 to 2 μm, and can be directly applied or spray-dried into a powdery resin. The emulsion polymerization method has a short polymerization period and is easy to control, and the obtained resin has a high molecular weight and a uniform polymerization degree, and is suitable for use as a polyvinyl chloride paste, an artificial leather or an impregnated product. The formulation of the emulsion polymerization is complicated, and the product has a high impurity content.
