Polyvinyl chloride (PVC) is a popular and versatile thermoplastic polymer widely used in construction, healthcare, electronics, and automotive industries, among others. The monomer unit that forms PVC is vinyl chloride (VC), which has the chemical formula C2H3Cl. The structure of the vinyl chloride monomer consists of two carbon atoms double-bonded to each other, with one carbon atom bonded to two hydrogen atoms and the other to a chlorine atom. This structure is what gives PVC its unique properties – durability, resistance to environmental degradation, and ability to be plasticized or softened with the addition of phthalates. In polymerization, multiple vinyl chloride monomers connect through the breaking of the double bond between the carbon atoms, forming long chains of PVC. The process of polymerizing VC into PVC can involve several methods, including suspension, emulsion, and bulk polymerization, each providing different characteristics to the final product.
