Polymerization of Vinyl Chloride to PVC
nCH2=CHCl → (–CH2–CHCl–)n
Tổng quan
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.
Ví dụ thực tế
PVC pipes, vinyl flooring, window frames, wire insulation, and credit cards are all made from this polymerization reaction.
Tầm quan trọng công nghiệp
Over 45 million tonnes of PVC are produced annually for construction, healthcare, automotive, and packaging applications.
