Polymerization of Vinyl Chloride to PVC
nCH2=CHCl → (–CH2–CHCl–)n
Overview
Vinyl chloride monomer (VCM) undergoes free radical addition polymerization to form polyvinyl chloride (PVC), the third most produced plastic worldwide. PVC is rigid by default but can be made flexible with plasticizers. Suspension polymerization is the most common industrial method.
Everyday Example
PVC pipes, vinyl flooring, window frames, wire insulation, and credit cards are all made from this polymerization reaction.
Industrial Importance
Over 45 million tonnes of PVC are produced annually for construction, healthcare, automotive, and packaging applications.
