Answer:
Biodegradable polymers are a special class of polymer that breaks down after its intended purpose by bacterial decomposition process to result in natural byproducts such as gases (CO2, N2), water, biomass, and inorganic salts.In the biological system, these polymers decompose or hydrolyse in the Presence of different enzymes. This means that they are biodegradable. Aliphatic polyesters are the common examples of biodegradable Polymers. It is a copolymer of 3-hydroxybutanoic acid and 3-hydroxypentanoic acid.
The common examples of aliphatic biodegradable polymers are polyglycolic acid(PGA), Polyhydroxy butyrate (PHB), Polyhydroxy butyrates-co-beta hydroxyl valerate( PHBV), Polycaprolactone(pcl), Nylon-2-nylon-6.
