Question

In the biodegradable copolymer PHBV (Poly $\beta$ -hydroxybutyrate-co- $\beta$ -hydroxyvalerate), the physical properties of the polymer can be altered by changing the ratio of its monomers. Which of the following monomers, when used in excess, specifically imparts greater flexibility to the resulting PHBV polymer?

Prashant Kotian · Accepted Answer

Correct answer: C. PHBV is a copolymer of 3-hydroxybutanoic acid ( -hydroxybutyric acid) and 3-hydroxypentanoic acid ( -hydroxyvaleric acid). The 3-hydroxybutanoic acid part provides stiffness to the polymer, while the 3-hydroxypentanoic acid ( -hydroxypentanoic acid) provides flexibility.
