Question

Write down a method of preparation of PVC?

Answer 1

Poly Vinyl Chloride (PVC) is prepared by addition (chain growth) polymerisation of vinyl chloride.
$nC{H}_2=\underset{Cl}{\underset{|}{C}}H\underset{\text{Pressure}}{\overset{\text{Peracid}}{\to }}[-C{H}_2-\underset{Cl}{\underset{|}{CH}}-{]}_n$
Vinyl chloride Poly Vinyl Chloride (PVC)
The monomer used is vinyl chloride ($C{H}_2=\underset{Cl}{\underset{|}{C}}H$). It is treated with peracid under pressure to obtain Poly Vinyl Chloride (PVC).
