Question
What are biodegradable polymers? Give examples.
Answer in Brief
Solution
1. The materials that are readily decomposed by microorganisms in the environment are called biodegradable.
2. Natural polymers degrade on their own after a certain period of time but synthetic polymers do not.
3. The biopolymers which disintegrated by themselves in biological systems during a certain period of time by enzymatic hydrolysis and to some extent by oxidation are called biodegradable polymers.
Examples:
- Polyhydroxy butyrate (PHB)
- Polyhydroxy butyrate-co-hydroxyl valerate (PHBV)
- Polylactic acid (PLA)
