염화 바이닐의 PVC 중합

nCH2=CHCl → (–CH2–CHCl–)n

개요

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.

일상 속 예시

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

산업적 중요성
