Question:
Which from following is a biodegradable polymer?
Which from following is a biodegradable polymer?
Show Hint
PHBV, a polyester of 3-hydroxybutanoic acid and 3-hydroxypentanoic acid, is biodegradable.
Updated On: Nov 13, 2026
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept
A biodegradable polymer breaks down by microbial action, for example the polyester PHBV.
Step 2: Check the structures
Option A shows repeating units with ester linkages containing methyl and ethyl groups, which is PHBV.\nOption B is polystyrene, C is a nitrile rubber-type polymer and D is PVC.
Final Answer:
The polyester PHBV shown in option A is biodegradable. \[ \boxed{\text{(A) }\text{PHBV (the polyester structure shown)}} \]
