Question

Which one of the following is not a condensation polymer ?

• A. Glyptal
• B. Dacron
• C. Neoprene
• D. Melamine

Answer 1

Answer: (C)

Condensation polymers are obtained by bifunctional molecules (monomers) with the elimination of smaller molecules whereas additional polymers are obtained from multiple bond containing monomers. Neoprene is a polymer of chloroprene $\left(C{H}_2=C(Cl)-CH=C{H}_2\right)$ so it is an addition polymer, not a condensation polymer.
