(1) nylon-6, 6
(2) nylon 2-nylon 6
(3) nylon-6
(4) Buna-S

Answer 1

Explanation:

Among those, the biodegradable polymer is

Nylon-2 Nylon-6

Answer 2

Nylon 2–nylon 6

Explanation:

Biodegradable polymers are a class of polymers whose chemical and physical characteristics undergo deterioration and completely degrade when exposed to microorganisms, aerobic, and anaerobic processes to result in natural byproducts such as gases, water, biomass, and inorganic salts.

• These biopolymers include proteins, polysaccharides, polyamides, nucleic acids or lipids which show completely different characteristics
• In given polymers nylon 2-nylon 6 is a polyamide.
• Formed by copolymerisation of glycine ($H_2N - CH_2 -COOH$) and aminocaproic acid ($H_2N-(CH_2)_5-COOH$).
• Hence nylon 2-nylon 6 is the biodegradable polymer.
