Polymerization of Vinyl Chloride to PVC

nCH2=CHCl → (–CH2–CHCl–)n

अवलोकन

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.

रोजमर्रा का उदाहरण

PVC pipes, vinyl flooring, window frames, wire insulation, and credit cards are all made from this polymerization reaction.

औद्योगिक महत्व

Over 45 million tonnes of PVC are produced annually for construction, healthcare, automotive, and packaging applications.
