Which of the following polymer has ester linkage?

A)  Nylon-66      

B)  PVC

C)  Terylene      

D)  SBR

Correct Answer: C

Solution :

[a] Nylon 66: It is an polyamide polymer. The monomers are adipic acid and hexamethylenediamine. [b] PVC: It is polyhalo-olefm. The monomer is vinyl chloride. \[(C{{H}_{2}}=\underset{\begin{smallmatrix}  | \\  Cl \end{smallmatrix}}{\mathop{C}}\,H)\] [c] Terylene: It is polyester having ester linkages. The monomers are ethylene glycol and terephthalic acid. \[\underset{ethylene\text{ }glycol}{\mathop{n(HO-C{{H}_{2}}-C{{H}_{2}}-OH)}}\,\] [d] SBR (styrene butadiene rubber): It is synthetic rubber. The monomers are 1, 3-butadiene and styrene.
