Which polymer has 'chiral' monomer(s)?

Which polymer has 'chiral' monomer(s)?

Step-by-step solution

Polymers	Monomers
1) $Buna – N$	${CH}_{2} = CH - CH = {CH}_{2} \text{\text{ and } }$ CN - CH = {CH}_{2}
2) Neoprene- ${\left[C{H}_{2} - CH = CCI - C{H}_{2}\right]}_{n} -$
3) NYLON $- 6,6$: $~ \left[CO{\left({CH}_{2}\right)}_{6}NH\right]N ~$	$H{O}_{2}C - {\left(C{H}_{2}\right)}_{4} - {CO}_{2}H \text{\text{ and } } {H}_{2}N - {\left(C{H}_{2}\right)}_{6} - N{H}_{2}$
4) In PHBV, both monomers have chiral centre.	$\left(3 - Hydroxbutanoicacid\right)\left(3 - Hydroxypertanoicacid\right)$
