Question

Which of the following polymers can be made by condensation polymerisation reaction?

• A. Dacron
• B. Nylon - $6,6$
• C. Bakelite
• D. Polyethylene

Answer 1

Answer: (A), (B), (C)

The correct options are
A Bakelite
B Dacron
C Nylon - $6,6$

Condensation polymers are formed by repeated condensation reactions between two different bi-functional or tri-functional monomeric units. In these polymerisation reactions, the elimination of small molecules such as water, alcohol, hydrogen chloride, etc. takes place.

Dacron, Nylon-6.6 and Bakelite are produced by condensation polymerisation.

On the other hand, Polyethylene is formed by breakage of the double bond and there is no elimination of molecules.
