It was introduced in 1934. Polyvinyl chloride was launched on the market in commercial quantities for the manufacture of various products. ,
But the most important period of progress of plastics happened in the 1950s to 1960s, when the era of invention and production of different types of plastics with diverse properties and applications was called a turning point in this industry. ,
In these times, scientists such as Ziegler from Germany or Nata from Italy clarified the principles and methods of polymerization and caused the emergence of new technology in the direction of making different polymers such as polyethylenes, polypropylenes, polyethers and epoxies and … they became
