Polymerization of Vinyl Chloride to PVC

nCH₂=CHCl → (–CH₂–CHCl–)_n

Visão geral

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.

Exemplo do cotidiano

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

Importância industrial

Mais de 45 milhões de toneladas de PVC são produzidas anualmente para construção, saúde, automóvel e embalagens.
