Identify the polymer from the following that is obtained by using...

Nylon-2-nylon-6 is an alternating polyamide copolymer synthesized from glycine and aminocaproic acid.

Glycine (H_2N-CH_2-COOH$) is an \alpha$-amino acid, whereas aminocaproic acid (H_2N-(CH_2)_5-COOH$) is an \epsilon$-amino acid.

Nylon-6 is formed from caprolactam.

PHBV is formed from 3-hydroxybutanoic acid and 3-hydroxypentanoic acid.

Bakelite is formed from phenol and formaldehyde.

Thus, Nylon-2-nylon-6 is the polymer obtained by using an $\alpha$-amino acid.

Answer: Nylon₂⁻ nylon6
