Which of the following monomers form biodegradable polymers?
(a) 3-hydroxybutanoic acid + 3-hydroxypentanoic acid
(b) Glycine + amino caproic acid
(c) Ethylene glycol + phthalic acid
(d) Caprolactum
Answers: (a), and (b).
Biodegradable Polymer: The polymers which are easily decomposed and not harmful for the environment are known as the biodegradable polymer.
e.g.,
(i) PHBV is obtained by condensation polymerisation of 3-hydroxybutanoic acid and 3-hxydroypentanoic acid.
