Question

# Explain the method of preparation of PVC (polyvinyl chloride).

For the preparation of polyvinyl chloride, the monomer used is vinyl chloride $\left( {C{H_2} = CHCl} \right)$.
$n\left[ {C{H_2} = CHCl} \right]\xrightarrow[{Pressure}]{{Peracid}}{\left[ { - C{H_2} - CHCl - } \right]_n}$
Note:PVC is a polymer with good insulator it can be used at some place for providing insulation from electric current. PVC is less stable at high temperature it starts decomposing when its temperature reaches at $140^oC$ or above.
