Which of the following is a condensation polymer?

(A)Nylon 6, 6✓ Correct
(B)Neoprene
(C)Buna-S
(D)Teflon

Answer: (A)

Solution

Nylon-6,6 is a condensation polymer: hexamethylenediamine and adipic acid join with loss of water. Neoprene, Buna-S and Teflon are all addition polymers formed without expelling any small molecule, so nylon-6,6 is the condensation polymer here.
