Which of the following is a biodegradable polymer?

A$$-\!\!\![\,HN-(CH_2)_6NHCO-(CH_2)_4-\overset{O}{\overset{||}C}\,]\!\!\!-_n$$
B$$-\!\!\![\,HN-(CH_2)_5-\overset{O}{\overset{||}C}]\!\!\!-_n$$
C
D$$-\!\!\![\,HN-(CH_2)_5CONH-CH_2-\overset{O}{\overset{||}C}\,]\!\!\!-_n$$
Correct Answer

Solution

The polymer shown in option (D) is a biodegradable polymer. This polymer is known as $$\text{Nylon-2-nylon-6}$$. It is a copolymer of $$\text{glycine} $$ and $$\text{w-amino caproic acid}$$. It contains polyamide linkages.

Hence, option D is correct.
