Polymerization of Vinyl Chloride to PVC

nCH2=CHCl → (–CH2–CHCl–)n

概要

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.

日常の例

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

産業上の重要性

PVCは建設、医療、自動車、包装用途として年間4,500万トン以上生産される。
