Biodegradable polymer which can be produced from glycine and aminocaproic acid is

  1. buna - N
  2. nylon 6, 6
  3. nylon 2-nylon 6
  4. PHBV

Answer

(3) nylon 2-nylon 6

Solution

As per NCERT, nylon 2–nylon 6 is an alternating polyamide copolymer of glycine (H2N-CH2-COOH) and amino caproic acid (H2N-(CH2)5-COOH), and it is biodegradable.

∵ PHBV is made from 3-hydroxybutanoic acid and 3-hydroxypentanoic acid; nylon 6,6 from hexamethylenediamine and adipic acid; buna-N from 1,3-butadiene and acrylonitrile.

∴ The polymer is nylon 2-nylon 6.
