PVC plastic is made by synthesizing vinyl chloride from acetylene gas and hydrogen chloride. In the early 1950s, it was produced by the acetylene calcium carbide method. In the late 1950s, it turned to the ethylene oxidation method with sufficient raw materials and low cost. At present, more than 80% of the PVC resin in the world is produced by this method. However, after 2003, due to the skyrocketing oil prices, the cost of acetylene calcium carbide method was about 10% lower than that of ethylene oxidation. Therefore, the synthesis process of PVC turned to acetylene calcium carbide method.


PVC plastic is made from liquid vinyl chloride monomer (VCM) by suspension, emulsion, bulk or solution process. The suspension polymerization process has mature production process, simple operation, low production cost, variety of products and wide application range. It has been the main method of producing PVC resin, accounting for about 90% of the world's PVC production equipment (the homopolymer also accounts for about 90% of the world's total PVC production). Followed by the emulsion method for the production of PVC paste resin. The polymerization reaction is initiated by a free radical, and the reaction temperature is generally 40 to 70 OC. The reaction temperature and the concentration of the initiator have a great influence on the polymerization rate and the molecular weight distribution of the PVC resin.
