Polymerization of Vinyl Chloride to PVC

nCH2=CHCl → (–CH2–CHCl–)n

概述

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.

日常示例

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

工业重要性

PVC每年产量超过4500万吨,广泛用于建筑管材、电线绝缘层、地板和医疗器械,是不可或缺的工业材料。
