Question:
Which one of the following monomers form biodegradable polymer?
Which one of the following monomers form biodegradable polymer?
Updated On: Apr 19, 2024
- Urea and formaldehyde
- Ethylene glycol and terephthalic acid
- $3$-hydroxybutanoic acid and $3$-hydroxypentanoic acid
- Phenol and caproic acid
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
3-hydroxybutanoic acid and 3-hydroxypentanoic acid are the monomer unit of PHBV (poly- $\beta$-hydroxybutyrate-co-$\beta$-hydroxyvalerate). P HBV is biodegradable polymers and can be degraded by microorganisms within a suitable period.

Biodegradable Polymers
Microorganisms destroy biodegradable polymers in an appropriate amount of time, ensuring that biodegradable polymers and their degraded products have a low environmental result. Enzyme-catalyzed processes shatter these polymers down into little segments, and microorganisms manufacture these enzymes.
Biodegradable Polymers: Examples
- Poly-β-hydroxybutyrate-co-β-hydroxy valerate (PHBV)
- Polylactic Acid (PLA)
- Poly (ε-caprolactone) (PCL)
- Nylon-2-Nylon-6
Biodegradable Polymers: Properties
- Can maintain strong mechanical unification until they are degraded.
- Degradation, in general, starts at the end groups because biodegradable polymers have exceptionally strong carbon backbones that are difficult to crack.
- Non-toxic in nature.
- Degradation rates can be controlled.
- Lack of crystallinity, which inhibits access to end groups.
- Hydrophilic polymers.
