Which of the following polymers is biodegradable?
A. Polyethylene
B. Polyvinyl chloride
C. Poly-beta-hydroxybutyrate-co-beta-hydroxyvalerate (PHBV)✓ Correct Answer
D. Nylon-6,6
💡 Solution & Explanation
PHBV is a biodegradable copolymer synthesized by bacteria, utilized as an eco-friendly alternative to conventional plastics because microorganisms can break it down into harmless byproducts. Polyethylene, polyvinyl chloride, and nylon-6,6 are synthetic polymers possessing high chemical resistance that make them non-biodegradable environmental pollutants.
