Answer 1

Answer:

Biodegradable polymers :

All those biopolymers which disintegrate by themselves in biological systems during certain period of time by enzymatic hydrolysis are called biodegradable polymers.

Example : Poly-p-Hydroxybutyrate-Co-p-Hydro- xyvalerate (PHBV)

Uses : These are used in

• packaging

• orthopaedic devices

• controlled drug release

• bacterial degradation.
