PVC is obtained by the polymerization of 

(1) Propane 

(2) Vinyl chloride 

(3) Styrene 

(4) Acetylene

Answer: (2) Polyvinyl chloride is produced by polymerization of the monomer vinyl chloride (VCM). Polyvinyl chloride, commonly abbreviated PVC, is the third most widely produced plastic, after polyethylene and polypropylene. PVC is used in construction because it is cheaper and stronger than more traditional alternatives such as copper or ductile iron. It can be made softer and more flexible by the addition of plasticizers, the most widely used being phthalates. In this form, it is used in clothing and upholstery, electrical cable insulation, inflatable products, and many applications in which it replaces rubber.
