Which of the following is not an example of a condensation polymer?

(A)Nylon 6,6
(B)Decron
(C)Buna-N✓ Correct
(D)Silicone

Answer: (C)

Solution

Buna-N is an addition copolymer formed by the polymerization of 1,3-butadiene and acrylonitrile without the elimination of small molecules. Nylon 6,6, Dacron (polyester), and silicones are all condensation polymers formed with the elimination of small molecules like water or HCl.
