Wired Faculty App

What are elastomers? Write the chemical equation to represent the preparation of Buna-S.

Solution

Elastomers: They are polymers in which polymer chains are held together by the weakest intermolecular forces. They can be stretched due to weak forces of attraction.
Buna-S can be prepared by reaction of 1, 3-butadiene and styrene in presence of sodium as a polymerising agent.
