Question
How is PHBV polymer prepared?
✓
Answer
It is a copolymer. The monomers $\beta$-hydroxy butyric acid ( 3 -hydroxy butanoic acid) and $\beta$-hydroxy valeric acid (3-hydroxy pentanoic acid) undergo polymerization to form PHBV polymer. It has an ester linkage. Hydroxyl group of one monomer forms ester link by reacting with carboxyl group of the other. Thus $PHBV$ is an aliphatic polyester i.e. poly $\beta$-hydroxybutyrate-co- $\beta$-hydroxy valerate (PHBV). It is a biodegradable polymer.
