Q.15 Which of the following monomers form biodegradable polymers?

(a) S-hydroxybutanoic acid+3-hydroxypentanoic acid

(b) Glycine + aminocaproic acid

(c) Ethylene glycol + phthalic acid

(d) Caprolactam


 

(a, b)

Biodegradable Polymer The polymers which are easily decomposed and not harmful to the environment are known as a biodegradable polymer.

e.g.

(i) PHBV is obtained by condensation polymerization of 3 hydroxybutanoic acids and 3 hxydroypentanoic acids.

(ii) Glycine and aminocaproic acid produce nylon-2 nylon-6 polymer.
