Question

The biodegradable polymer is :

• A. Nylon 6,6
• B. Nylon 2–nylon 6
• C. Nylon-6
• D. Buna-S

Answer 1

The correct option is B Nylon 2–nylon 6

Aliphatic polyesters are one of the important classes of biodegradable polymers. Some important examples are given below:
1. Poly β-hydroxybutyrate-co-β-hydroxy valerate (PHBV)
It is obtained by the copolymerisation of 3-hydroxybutanoic
acid and 3-hydroxypentanoic acid.
2. Nylon 2–nylon 6: It is an alternating polyamide copolymer of glycine $(H_{2}N–C{H}_2–COOH)$ and amino caproic acid $\left(H_{2}N\right(C{H}_2{)}_{5}COOH)$ and is biodegradable.
