1 Answer

Answer :

(2) Vinyl chloride Explanation: Polyvinyl chloride is produced by polymerization of the monomer vinyl chloride (17CM). 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.
