Question

Which of the following is the biodegradable polymer of polyamide class ?

• A. Nylon - $6,6$
• B. Nylon - $2$ - nylon - $6$
• C. Dextran
• D. PHBV

Answer 1

The correct option is B Nylon - $2$ - nylon - $6$

Biodegradable is defined as being able to be broken down by other living organisms. Nylon-$2$-nylon-$6$, Dextran and PHBV are biodegradable, whereas, Nylon - $6,6$ is non-biodegradable.

However, Dextran and PHBV, both are polyesters and Nylon-$2$-nylon-$6$ is a polyamide. Dextran is formed by the polymerization of many glucose molecules.
