Delhi UMET/DPMTDelhi UMET/DPMT 2003
Solution:
[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.
$(CH_2 = \underset{\overset{|}{C}l}{CH})$
[c] Terylene: It is polyester having ester linkages.
The monomers are ethylene glycol and terephthalic acid.
$\underset{\text{ethylene glycol}}{n(HO - CH_2 - CH_2 - OH)}$
[d] SBR (styrene butadiene rubber): It is synthetic rubber.
The monomers are $1, 3$-butadiene and styrene.
