What are the monomers used for preparation of PHBV?
Options
- ACellulose xanthate and NaOH.
- B1,3-Butadine and styrene
- C-Hydroxy butyric acid and -Hydroxy valeric acid
- DEthylene glycol and phthalic acid
Correct answer
C. -Hydroxy butyric acid and -Hydroxy valeric acid
Step-by-step solution
PHBV stands for Poly -hydroxybutyrate-co- -hydroxyvalerate. It is a biodegradable copolymer obtained by the copolymerisation of 3-hydroxybutanoic acid ( -hydroxybutyric acid) and 3-hydroxypentanoic acid ( -hydroxyvaleric acid). Answer: -Hydroxy butyric acid and -Hydroxy valeric acid
