PVC can be divided into: general-purpose PVC resin, high-polymerization PVC resin, cross-linked PVC resin. The general-purpose PVC resin is formed by polymerization of vinyl chloride monomer under the action of an initiator; the high polymerization degree PVC resin refers to a resin obtained by adding a chain extender in a vinyl chloride monomer polymerization system; the crosslinked PVC resin is A resin obtained by polymerizing a crosslinking agent containing a diene and a polyene into a vinyl chloride monomer polymerization system.

PVC is prepared by free radical addition polymerization. The polymerization method is mainly divided into suspension polymerization method, emulsion polymerization method and bulk polymerization method. The suspension polymerization method is mainly used, accounting for about 80% of the total PVC production. The pure water, the liquefied VCM monomer and the dispersing agent are added to the reaction vessel, and then the initiator and other auxiliary agents are added. After the temperature is raised to a certain temperature, the VCM monomer undergoes radical polymerization to form PVC particles. Continued agitation results in uniform particle size and suspension of the resulting particles in water. In addition, the resin for PVC paste is produced by the microsuspension method, and the product properties and pasteability are good.
