PHBV stands for Poly($3$-hydroxybutyrate-co-$3$-hydroxyvalerate).

It is a biodegradable aliphatic polyester formed by the copolymerisation of $3$-hydroxybutanoic acid and $3$-hydroxypentanoic acid.

The structure of $3$-hydroxybutanoic acid is $C{H}_3-CH(OH)-C{H}_2-COOH$.

The structure of $3$-hydroxypentanoic acid is $C{H}_3-C{H}_2-CH(OH)-C{H}_2-COOH$.

These two monomers undergo condensation polymerisation to form PHBV.

Answer: $3$-hydroxybutanoicacid and $3$-hydroxypentanoicacid
