Question

Write a balanced chemical equation to represent the addition polymerization of 1,1-dichloroethene. The product of this reaction is Saran, used as a plastic wrap

Short answer

The reaction representing the addition polymerization is as shown:

Formation of saran

Step-by-step solution

Polymer

If one of the hydrogen atoms of the ethene monomer unit is replaced with a different type of atom or functional group, the plastics that form upon polymerization have different properties.

Explanation

The addition polymerization of 1,1-dichloroethylene yields saran which is used as a plastic wrap. Here monomer is 1,1-dichloroethylene and the polymer is saran (polyvinylidene chloride).

The reaction shows the formation of saran from 1,1-dichloroethylene is as:

Formation of saran
