|Polyvinyl chloride also known as PVC is a thermoplastic material derived from common salt and fossil fuels.
After polyethylene, PVC is the most important plastics. It was first discovered by Henri Victor Regnault in 1835, and after him one more time Eugen Baumann in 1872. Both times the polymer appeared as a white solid substance in the bottle vinyl chloride which are left in the sunlight.
There were a few attempts of PVC commercialization, however, the material was difficult to process. Scientists Valo Semon’s experiments have led to the creation of plasticization methods, by mixing PVC with various additives. The result was a material, which was easy to handle, and commercial use was wide.
PVC is mostly produced with method called the suspension polymerization process.
The polymerization is carried out at a low pressure of below 1 MPa, and temperature of 30 to 80 °C in the presence of an inorganic or organic peroxide activator.
