Question

Which of the following pair of monomers are used in preparation of PHBV ?

• A. $\beta -$ hydroxy valeric acid, amino caproic acid
• B. $\beta -$ hydroxy butyric acid, $\beta -$ hydroxy valeric acid
• C. $\beta -$ hydroxy butyric acid, adipic acid
• D. Lactic acid, adipic acid

Answer 1

The correct option is B $\beta -$ hydroxy butyric acid, $\beta -$ hydroxy valeric acid

PHBV (poly $\beta$-hydroxy butyrate - $CO-\beta -$ hydroxy valerate) is a biodegradable copolymer of $\beta$-hydroxy butyric acid and $\beta$-hydroxy valeric (or pentanoic) acid.
