Question

Which of the following polymer has ester linkage?

• A. Nylon-66
• B. PVC
• C. Terylene
• D. SBR

Answer 1

Answer: (C)

[a] Nylon $66$: It is an polyamide polymer.
The monomers are adipic acid and hexamethylenediamine.
[b] PVC: It is polyhalo-olefin.
The monomer is vinyl chloride.
$(C{H}_2=\underset{\stackrel{|}{C}l}{\mathrm{CH}})$
[c] Terylene: It is polyester having ester linkages.
The monomers are ethylene glycol and terephthalic acid.
$\underset{\text{ethylene glycol}}{n(HO-C{H}_2-C{H}_2-OH)}$
[d] SBR (styrene butadiene rubber): It is synthetic rubber.
The monomers are $1,3$-butadiene and styrene.
