The Improvement of Polyvinyl Chloride Synthesis Using Different Approaches
Abstract: Polyvinyl chloride (PVC) is produced by the polymerization of the vinyl chloride monomer either by direct chlorination of olefins or by addition of hydrogen chloride to acetylene. The polymerization conditions are: heat, peroxides or oxidizing agents with basic structure as -CH2CHCl.CHCl-CH2.CHCl-. Polyvinyl chloride is a thermoplastic and its plasticity can be increased by incorporating ‘plasticizers’ of relatively low molecular weight organic materials during molding or extrusion. PVC has high hardness …
