Chemistry - Polymer Question with Solution | TestHub

PHBV (Poly $\beta$-hydroxybutyrate-co-$\beta$-hydroxyvalerate) is a biodegradable aliphatic polyester.

It is obtained by the copolymerization of 3-hydroxybutanoic acid ($\beta$-hydroxybutyric acid) and 3-hydroxypentanoic acid ($\beta$-hydroxyvaleric acid).

Therefore, the monomers of PHBV are $\beta$-hydroxybutyric acid and $\beta$-hydroxyvaleric acid.

Answer: $\beta$ - hydroxy Butyric acid and $\beta$ - hydroxy Valeric acid
